Improved upper bound on the bit error probability of turbo codes for ML decoding with imperfect CSI in a Rayleigh fading channel
نویسندگان
چکیده
− In this paper, we investigate an improved upper bound on the bit error probability of turbo codes for the maximum likelihood (ML) decoding with imperfect channel state information (CSI) in a fully interleaved Rayleigh fading channel. The upper bound is based on recently introduced Viterbi & Viterbi bound and is also compared with iterative decoding using the Log-MAP algorithm. It is shown that the upper bound well approximates the simulation results of the iterative decoding below the BER of . 5 10

Turbo Codes: The Issue of Average Union Upper Bound under Imperfect Channel State Information in Rayleigh Fading Channels
The potential of turbo codes to demonstrate excellent performance in the region of low signal to noise ratio is now a familiar fact. The idea of turbo codes was first introduced by Berrou and was based on the clever utilization of the existing decoding mechanism of BCJR with a change in the encoder by introducing feedback and an interleaver in the overall scheme. Since then, these powerful forw...
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 کاملOn improved bounds on the decoding error probability of block codes over interleaved fading channels, with applications to turbo-like codes
We derive here improved upper bounds on the error probability of block codes which are transmitted over fully interleaved Rician fading channels, coherently detected and maximum likelihood decoded. We assume that the fading coefficients during each symbol are statistically independent (due to a perfect channel interleaver), and that perfect estimates of these fading coefficients are provided to...
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 کاملAn Upper Bound of Soft Decode and Forward Relaying Over Rayleigh Fading Channels
In this paper, we investigate a distributed turbo code (DTC) scheme dedicated to L-relay channels operating in the soft-decode-and-forward (soft-DF) mode. At the destination, the received replicas are combined using the maximal ratio combining (MRC). Then, we define the explicit upper bound for error rate assuming Binary phase shift keying (BPSK) transmission for fully interleaved channels with...
