Much attention has been paid on reducing the cost in these networks. One approach is to adopt Ethernet passive optical network (EPON) architectures in an access network. In this paper a solution of EPON of Broadcasting/WDMA architecture is presented, which is based on several low-cost DWDM devices developed newly by authors, including the precise-wavelength DWDM-LD, DWDM demultipler with interleaver, DWDM receiver array, and dual-window broad-band coupler. | ind_Latn | 13,400 |
Double chip waveforms for asynchronous DS-CDMA systems with random signature sequences | In an asynchronous DS-CDMA system using random signature sequences and correlation receivers, the signal-to-interference-plus-noise ratio (SINR) at the output of each correlation receiver depends on the shape of the chip waveform employed. The use of double chip waveforms instead of a single chip waveform is investigated, in order to increase the SINR performance. An analytical expression for the SINR when double chip waveforms are used is obtained. To evaluate the performance of the proposed technique, an extension to Holtzman's approximation of the error probability for the case of double chip waveforms and signalling over an additive white Gausian noise channel is derived. Numerous numerical examples are given to demonstrate the advantage of using double chip waveforms over the single chip waveform. Moreover, the advantage of using double chip waveforms for improving the SINR performance over a multipath Rayleigh fading channel is also demonstrated. | A best and efficiently to provide a system and method capable of setting up a resource by the receiving device and the wireless network.

An Efficient Partial Power Processing DC/DC Converter for Distributed PV Architectures | In this paper, a dc/dc power converter for distributed photovoltaic (PV) plant architectures is presented. The proposed converter has the advantages of simplicity, high efficiency, and low cost. High efficiency is achieved by having a portion of the input PV power directly fed forward to the output without being processed by the converter. The operation of this converter allows for a simplified maximum power point tracker design using fewer measurements. The stability analysis of the distributed PV system comprised of the proposed dc/dc converters confirms the stable operation even with a large number of deployed converters. The experimental results show a composite weighted efficiency of 98.22% with very high maximum power point tracking efficiency. | We present a new order statistics based diversity combining scheme (OSDC) for combining a set of independently fading signal amplitudes. The OSDC orders all the received signal amplitudes and uses only the two strongest signals in the combining process. The decision as to whether to use only the strongest or both the strongest and the next strongest is mane depending on the relative strengths of these two highest order statistics. Signal-to-noise ratio performance of the new scheme is compared with that of the traditional schemes such as, selection combining, maximal ratio combining, equal gain combining, and a second order selection combining (SC2), for three channels, namely Rayleigh, Nakagami and exponential. The results show that OSDC performs as well as SC2. | eng_Latn | 13,403 |

We assume that there are multiple resolvable paths in the frequency selective fading channel. Analytical results show that in addition to spatial diversity, another diversity gain called multipath diversity is achievable. Performance criterion for full space multipath diversity gain is analyzed. We consider both the case that the receiver has the ideal channel state information and the case that there are errors in the channel state information available to the receiver. A RAKE receiver is used in the CDMA system to gain the multipath diversity. We derive the generalized RAKE receiver structure for the space-time block coding (STBC) coded wideband CDMA systems.

A wideband mixer designed with low conversion loss through the entire W-band | In this paper, a mixer is designed with low conversion loss through the entire W-band. A novel low pass filter is proposed and used to select the intermediate frequency signal with large rejection of the local oscillator (LO) and radio frequency (RF) signals. A single slot is added on the LO passage to achieve impedance matching in a narrow frequency band, while two slots and one metal strip are added on the RF passage to achieve impedance matching in a wide frequency band. The detailed design process is presented, where a more accurate full-wave simulation model of the adopted diode is suggested. Difference in performances can be obtained by changing the key sizes of the matching structures. One sample is fabricated, and the measured conversion loss is less than 9.5 dB through the entire W-band (from 75 to 110 GHz) under fixed LO condition. The measured return loss of RF port is between 5 and 13.5 dB. | Since the introduction of adaptive equalizers in digital communication systems by Lucky [1], much progress has been made. Due to their particular constraints many new and different concepts in the wireless domain have been proposed. The wireless channel is typically time and frequency dispersive, making it difficult to use standard equalizer techniques. Also, due to its time varying nature, long transmission bursts may get corrupted and require a continuous tracking operation. Thus, transmission is often performed in short bursts, allowing only a limited amount of training data. Furthermore, quite recently, advantages of the multiple-input multiple-output character of wireless channels have been recognized. This chapter presents an overview of equalization techniques in use and emphasizes the particularities of wireless applications. | eng_Latn | 13,407 |
Role of joint antenna-channel dispersions on UWB energy capture in pulsed schemes | It is currently assumed that distorting antennas are less performant than non distorting ones for pulse based ultra wide band (UWB) schemes. By systematically comparing the received signal to noise ratio (SNR) of distorting and of ideal antennas, we show here that such a belief is correct for coherent detection in line of sight or low multipath density channels, but not for dense channels. This statement is based on a simple discrete time analytical model of the input-output relation, and on simulations involving measured antennas and either measured channels or IEEE 802.15.3a simulated channels. In the case of energy integrating incoherent detection, antenna dispersion is also not a problem. | The invention relates to the field of communication systems, in particular to a wireless communication system used for multiple access. The wireless communication system comprises a user experience system and a mobile system controlled by the user experience system. According to the invention, power consumption of a wireless electric receiver in a multiple access wireless system can be reduced; optimally, level of required control signals is received and decoded, so that the level can be reduced to the lowest level; and in addition, access time to space of the receiver is reduced to the greatest extent, so power consumption is reduced, and loss of performance or receiving quality can be avoided. | eng_Latn | 13,408 |

An internal tunable matching network enables dual-band gain compensation to achieve a flat frequency response. This is realized using individually biased and matched diodes as variable load for a 90° hybrid coupler. The approach is similar to a reflection-type phase shifter, resulting in the ability to change the effective input impedance throughout capacitive, resistive and inductive behavior.

Energy analysis of semi-passive control for an aeroelastic plate-like wing using shunted piezoelectric materials | The use of piezoelectric materials in vibration control problems has been widely investigated over the last years. The main control techniques using piezoelectric materials are the active and passive ones. In the particular case of aeroelastic control, passive piezoelectric networks have a weak capability of improving the flutter envelope. Although active systems can achieve good control performance, the potential large amount of power required for actuation is an important issue. The synchronized switch damping techniques were developed to overcome the drawbacks of passive and active control. These nonlinear techniques increase the electromechanical conversion and enhance the shunt damping. In this article, an energy flow analysis is employed to investigate the effects of two switch damping techniques on the aeroelastic behavior of a plate-like wing in two case studies. In the first one, the energy flow analysis is presented for the base excitation condition without aerodynamic influence. The working pri... | A multihop regenerative relay system is considered. We explore adaptive power allocation (PA) under a total power constraint to minimize the system error probability when the perfect channel state information (CSI) is known at the transmitters. We propose adaptive PA schemes with limited feedback when the transmitters have no perfect knowledge of CSI. Simulation results demonstrate the good performance of the proposed PA scheme with perfect CSI. When no perfect CSI is available at the transmitters, the proposed PA schemes with a small number of feedback bits are able to achieve very close performance to the adaptive PA with perfect CSI. | eng_Latn | 13,410 |

Broad-band modeling of a realistic power converter shield for electric vehicle applications | This paper deals with the broad-band modeling of a realistic power converter shield used in an electric vehicle. To validate such a model, comparisons between computation and measurements are required. As it is not practical to characterize experimentally the true radiation of a power converter through its enclosure, a reciprocal approach has been defined in which the enclosure is illuminated by a plane wave (receiving configuration). The associated experimental setup has been carefully defined and tested. At low frequency, the model is based on radiation through apertures in a simple cavity. At higher frequency, the Aseris-BE code, which is based on the boundary integral equations technique, has been used for computation. An optimal and realistic mesh of the enclosure suitable for the Aseris-BE code has been built by making numerous comparisons between computation and measurements, which have shown how to improve the mesh. | This paper presents a full analytical characterization of the optimal joint downlink rate and power assignment for maximal total system throughput in a multi cell CDMA network. The paper has three main contributions. First, we provide an explicit and exact characterization of the structure of the optimal rate and power assignment: in a network with N base transmitter stations (BTSs) either all mobiles have maximum rate, or in k BTSs all mobiles have maximum rate and the other BTSs transmit at maximum power, or N-1 stations transmit at maximum power. Second, we give a characterization of the optimal rate assignment in each cell. Third, we give an exact algorithm for solving the rate and power assignment problem and a fast and accurate heuristic algorithm for power and rate assignment to achieve maximal downlink throughput in a multi cell CDMA system. | eng_Latn | 13,414 |
Extremely low-power, multi-Gigabit electrical signaling for parallel optical modules | This paper describes a physical interface for short distance electrical links that are typically used to link parallel optical modules into the system. This interface, called minimal power link (MPL), significantly reduces power consumption by reducing the transmit signal strength and adopting a novel electrical receiver circuit. In addition, MPL interface reduces electromagnetic emissions leading to reduced EMI - an important consideration in densely packaged server platforms. | This paper explains the way how to use the opto-coupler of interface grade with SPI bus in the control system in order to strengthen the noise rejection feature of the system. | eng_Latn | 13,415 |
Simulations of the dielectric constant of bonding materials and field emission properties of CNT cathodes | The effect of the dielectric constant (k) of bonding materials in a screen-printed carbon nanotube (CNT) cathode on the field enhancement factor was investigated for high-efficiency CNT cathodes using the ANSYS software. The values obtained by a simulation study were compared to the experimental results obtained for screen-printed CNT cathodes. The field enhancement factor increased as the dielectric constant decreased, reaching a maximum value at a dielectric constant of 1, the value for a vacuum. The findings indicate that the larger sheet resistance of the bonding materials, after the firing process, can be attributed to the larger emission current of the CNT cathode. From these results, it was concluded that the best bonding materials for screen-printed CNT cathodes should have a low dielectric constant and a high sheet resistance. This finding can be used as criteria for selecting bonding materials for use in CNT pastes for highly efficient CNT cathodes. | In soliton communication systems, the continuous nonlinear spectrum, ideally zero, is conventionally ignored at the receiver. In this paper, we exploit correlation between the received continuous spectrum and perturbations of the discrete soliton eigenvalue. We propose four estimation schemes, classified into two categories, one based on the nonlinear Fourier transform (NFT) and the other based on minimum Euclidean distance. Both categories comprise two schemes, one that exploits the received continuous spectral function to achieve improved estimation and one that does not. Numerical simulations demonstrate that significant reduction in estimation error can be achieved when the continuous spectrum is exploited, translating into improved information transmission rates of up to ${\text{46}}\%$ compared to the reference NFT-based scheme. | eng_Latn | 13,416 |
U-Shape Slots Structure on Substrate Integrated Waveguide for 40-GHz Bandpass Filter Using LTCC Technology | Millimeter-wave (mmW) bandpass filter using substrate integrated waveguide (SIW) is proposed in this paper. The propagation constants of three different types of electromagnetic bandgap (EBG) units are discussed and compared with their passbands and stopbands performance. The slotted-SIW unit shows a very good lower stopband and upper stopband performance. The mmW bandpass filter with three cascaded uniform slotted-SIW-based EBG units is constructed and designed at 40 GHz. The extracted coupling coefficient ( ${K}$ ) and quality factor ( ${Q}$ ) are used to determine the filter circuit dimensions. To prove the validity, the previous proposed structure is fabricated in a single circuit layer using low-temperature co-fired ceramic technology and measured at 40 GHz, respectively.

[Percutaneous transhepatic cholecysto-lithotripsy]. | Authors were the first in Hungary to perform the percutaneous transhepatic cholecystolithotripsy for the removing of gallbladder stones. The method can be performed easily with the necessary skill and it is not too troublesome for the patients. They present their beginning experience. | The design of the LTE physical layer (PHY) is heavily influenced by the requirements for high peak transmission rate (100 Mbps DL/50 Mbps UL), spectral efficiency and multiple channel bandwidths (1.25–20 MHz). Unfortunately, the existing WCDMA turbo interleaver does not permit an efficient high throughput implementation. That is why the 3rd Generation Partnership Project (3GPP) has proposed the quadratic polynomial permutation (QPP) interleaver to rectify this situation. In this paper, we will study the performances of QPP interleaver for LTE encoder channel for different configurations of LTE system and we study the effect of LTE channel turbo encoder for the transmission over a wireless multipath channel. | eng_Latn | 13,418 |
A method to reduce the peak power with signal space expansion (ESPAR) for OFDM system | OFDM (orthogonal frequency division multiplexing) is an effective technique for high data rate wireless transmission. However, the OFDM system has a problem with the peak to average power ratio (PAPR) being very high. A high PAPR can cause severe distortion when transmitted through a nonlinear device. Therefore, because extreme power amplifier specification is required, high power consumption and large hardware is required. We propose a new method called ESPAR (Expansion of the signal Space for Peak to Average ratio Reduction) in order to reduce the peak power. ESPAR expands the signal space by modulating some subcarriers and not modulating the other subcarriers. The proposed system selects the symbol patterns with low signal power in the expanded signal space and transforms data sequences to the pattern. We evaluate the characteristics of the proposed system by computer simulation and show the advantage of ESPAR. | Ecoregion-based variable-exponent taper equations for white spruce (Picea glauca (Moench) Voss) were validated on independent tree sectioning data sets. Criteria used for model validation were briefly reviewed, along with applicable interpretations. Examination of the validation plots and statistics indicated that the mean prediction biases were small and very close to zero (−0.0058 ≤ ē ≤ 0.0247; −0.03% ≤ ē% ≤ 0.20%), and the mean squared error of prediction was low. The agreement between observed and predicted values from the taper equations was strong and obvious, and was consistent across the size classes of the predicted values. Approximately 99% of the total variation in both the diameter inside bark predictions and volume predictions were explained by the application of the fitted taper equations.

Antenna array geometry optimization for a passive coherent localisation system | Passive Coherent Localisation (PCL), also known as Passive Radar, making use of RF sources of opportunity such as Radio or TV Broadcasting Stations, Cellular Phone Network Base Stations, etc. is an advancing technology for covert operation because no active radar transmitter is required. It is also an attractive addition to existing active radar stations because it has the potential to discover low-flying and low-observable targets.

Asymptotic Throughput Analysis on Opportunistic Cophasing System with Single-Beam Transmission | Different from the opportunistic beamforming system (OBS) that randomizes both amplitude and phase of its beamforming vector, the opportunistic cophasing system (OCS) randomizes the phase only, which significantly reduces the demands on the dynamic range of power amplifiers. Focusing on the multi-user case of the OCS system, we give an asymptotic analysis on the system throughput under Rayleigh fading channels, based on the theory of extreme order statistics.

MORE ON SOLAR-LIKE OSCILLATIONS IN ETA BOO | We recently reported strong evidence for solar-like oscillations in the G0 IV star eta Boo (Kjeldsen et al. 1995, AJ 109, 1313). We measured small temperature fluctuations produced by oscillations through their effect on the equivalent widths of the Balmer lines. Here we address several issues that were raised at this conference. In particular, we show a power spectrum made without applying a high-pass filter to the observations. This spectrum shows increased noise at low frequencies, as expected, and the oscillation signature is still clearly visible. | Abstract Optical wireless communication technologies are finding a greater interest and wider attention within the research community of late.

An efficient boundary element algorithm for multi‐frequency acoustical analysis | In this article, a new boundary element algorithm in acoustics is proposed. This new algorithm uses a so‐called ‘‘Green’s function interpolation technique’’ so that it is ideally suited to a multi‐frequency analysis. In the numerical implementation of this new algorithm, the Green’s function used in the boundary integral equation is interpolated by a set of shape functions. Numerical integration is then confined to a frequency‐independent part only, and hence, is carried out only once at the first frequency of a multi‐frequency run. At subsequent frequencies, only the nodal values of the Green’s function have to be re‐calculated for the formation of the boundary element coefficient matrices. Compared to the recently developed ‘‘frequency interpolation technique,’’ this new algorithm requires much less disk space and can be easily extended to half‐space problems and problems with planes of symmetry. | A new technique based on adaptive code-to-user allocation for interference management on the downlink of BPSK based TDD DS-CDMA systems is presented. The principle of the proposed technique is to exploit the dependency of multiple access interference on the instantaneous symbol values of the active users. The objective is to adaptively allocate the available spreading sequences to users on a symbol-by-symbol basis to optimize the decision variables at the downlink receivers. The presented simulations show an overall system BER performance improvement of more than an order of a magnitude with the proposed technique while the adaptation overhead is kept less than 10% of the available bandwidth. | eng_Latn | 13,426 |
Broad Null Steering by Phase only Perturbation Using Immune Algorithm | Investigations on broad null steering by only phase perturbation are presented in this paper using immune algorithm (IA) for linear array. Broad null steering in antenna pattern helps to reduce channel interference due to less energy being transmitted at unwanted directions. Phase controlling for broad null steering is relative easy realizing comparing with amplitude or elements’ position controlling. IA is an efficient approach to escape from local convergency for muti-objective optimization with the antibody colony’s diversity is enhanced by using Logistic mapping for initial colony and Gauss function for mutation operator. In this paper, excitation phases are setted as antibodies optimizing for steering broad nulls with specified width at specified directions. Well simulation results show the availability of broad nulling by phase only controlling and the superior global search capability of the improved IA. | In this paper, we propose a new network immunization strategy for high clustering networks based on distributed autonomous entities which self-regulate their diffusion in the network. The advantage of a Self Regulating approach is that it can be applied to decentralized, unknown and dynamic networks. This strategy has been tested on several widely accepted benchmarks, and preliminary results are presented and discussed. | eng_Latn | 13,427 |
Channel Spacing dan Signifikansinya terhadap Performansi Jaringan DWDM dan SCM/WDM Radio over Fiber | Channel spacing is the important thing in order to determine the network capacity. The smaller channel spacing will give rise to the higher capacity. Moreover, the channel spacing is needed to avoid Optical Bit Interference. In this paper, minimum channel spacing obtained was 0.2 nm which generate the BER smaller than 10 -12 , so that it meets the International Telecommunication Union requirement. The DWDM network model could be implemented with good performance up to 100 km of optical fiber (without amplifier), whereas the SCM/WDM network model up to 90 km (without amplifier). Keywords : Channel Spacing, DWDM, SCM/WDM, Radio over Fiber | We experimentally demonstrate the efficiency of nonbinary GF(3)/GF(32) LPDC-coded non-uniform 9-QAM. We propose the non-uniform design method and low-complexity decoder. The proposed 9-QAM has >3dB gain in symbol OSNR compared to traditional binary LDPC-coded star-8-QAM. | ind_Latn | 13,428 |
Observations on Temperature and Temperature Patterns of the Gingiva: II. Estimations of the Error in Measurement | The diagnostician may expect an error associated with the measurements of clinical parameters. It is important to know how precise these measurements are. The purpose of this study was to make an estimation of the measurement error by comparing repeated measures of the same site. Six dental hygiene students were examined for gingival and sublingual temperatures as well as pocket depths and sulcular bleeding. All measurements were recorded twice. The maximum error associated with 95% of the temperature data and the average error were calculated as 1.3°C and 0.65°C, respectively. The probabilities of making a correct assessment of pocket depth and of sulcular bleeding were computed to be 0.864 and 0.840, respectively. The need for repeated measures was statistically analyzed. It can be concluded from our data that the thermocouple thermometer used in this study is a suitable instrument for measuring the gingival temperature. However, it is necessary to acquire a higher level of precision for the assessment ... | This paper deals with the optimization of multicarrier modulation technique using bit and power loading algorithm. The results from channel spectrum sensing are exploited for the optimization, having in mind the sensing imperfection. The simplest and most common method of spectrum sensing - the energy detection principle based periodogram method is considered. The new modified version of greedy algorithm has been proposed in order to limit the potential interferences caused by the imperfect spectrum sensing and resulting improper frequency band allocation, to cognitive radio primary users. As the inputs to the optimization, the measured TV band signals have been used. In order to get the real data samples, a Humax F3-FOX T receiver intermediate frequency signal was digitized using a GaGe CompuScope 12400 analog input PC card. | eng_Latn | 13,429 |
