Soft decision-directed MAP estimate of fast Rayleigh flat fading channels
نویسندگان
چکیده
In this letter, an iterative receiver with soft-decision feedback is derived by using the expectation–maximization algorithm for maximum a posteriori estimate of fast Rayleigh flat fading channels. Simulation results indicate that in a fast fading environment, the derived receiver can perform better than an iterative receiver with hard-decision feedback.

A Blind Hammerstein Diversity Combining Technique for Flat Fading Channels
Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...
متن کاملPerformance of Turbo Codes with Max-Log-MAP Decoding on Rayleigh Fading Channels
In this paper we investigate performance of turbo codes with Max-Log-MAP decoding on slow, flat Rayleigh fading channels. In order to simplify decoding algorithm implementation for a fading channel, the Gaussian distribution is applied to a channel metric. By means of computer simulations, we estimate BER of turbo codes on fully-interleaved and correlated channels with ideal CSI and without CSI...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملSymbol-by-symbol MAP demodulation of CPM and PSK signals on Rayleigh flat-fading channels
Demodulation using the symbol-by-symbol maximum a posteriori probability (MAP) algorithm is presented. The algorithm is derived for the case of continuous phase modulation (CPM) signals transmitted over Rayleigh flat-fading channels, and a corresponding receiver structure is specified. It is shown that the MAP algorithm requires computing, for each trellis branch, the sum of the products of the...
متن کاملC. Komninakis and R. D. Wesel: Joint Iterative Channel Estimation and Decoding in Flat Correlated Rayleigh Fading
Abstract— This paper addresses the design and performance evaluation with respect to capacity of M-PSK turbo-coded systems operating in frequency-flat, time-selective Rayleigh fading. The receiver jointly performs channel estimation and turbo decoding, allowing the two processes to benefit from each other. To this end, we introduce a suitable Markov model with a finite number of states, designe...
