Analysis of Random Regular LDPC Codes on Rayleigh Fading Channels
نویسندگان
چکیده
Low-density parity check (LDPC) codes of small, realizable size and regular form are analyzed in different multipath fading conditions. The multipath fading conditions vary from uncorrelated channels (with and without channel state information (CSI)) to a correlated land mobile channel at a frequency of 900 MHz. The effects of an external channel interleaver and varying mobile speed in a correlated fading channel are investigated. Obtained results show that the channel interleaver does not provide substantial improvement in the performance of the codes. However, the increasing speed of a mobile in a correlated channel can provide better bit error rate (BER) performance.

Performance of Spatially-Coupled LDPC Codes and Threshold Saturation over BICM Channels
We study the performance of binary spatiallycoupled low-density parity-check codes (SC-LDPC) when used with bit-interleaved coded-modulation (BICM) schemes. This paper considers the cases when transmission takes place over additive white Gaussian noise (AWGN) channels and Rayleigh fast-fading channels. The technique of upper bounding the maximum-a-posteriori (MAP) decoding performance of LDPC c...
متن کاملDigital Fountain Codes System Model and Performance over AWGN and Rayleigh Fading Channels
Digital fountain codes were originally packet-level forward erasure codes, but researchers have found that they are good at correcting bit errors. Modern LDPC and turbo codes have been shown to approach the Shannon limit. However, they are fixed rate codes and cannot well satisfy the Internet services that may encounter variable loss rates or asynchronous data access. For both packet and bit le...
متن کاملProduct Accumulate Codes on Fading Channels
Product accumulate codes are a special case of differentially coded low density parity check (LDPC) codes. This work analyzes the noncoherent performance of PA codes and general differentially-coded LDPC codes on flat Rayleigh fading channels using extrinsic information transfer charts, and proposes a convergence-constraint method to design good LDPC ensembles matched to differential coding.
متن کاملA LDPC-Coded Distributed Alamouti Space-time Relay Cooperation Scheme over Rayleigh Fading Channels
An efficient distributed Alamouti Space-time coded relay cooperation scheme is proposed over a Rayleigh fading channel, where structured irregular systematic low-densityparity-check (LDPC) codes are employed. In the known channel state information (CSI) scenario, a concatenation of combiner and joint iterative decoder is effectively carried out in the destination. The theoretical analysis and n...
متن کاملPerformance analysis and code optimization of low density parity-check codes on Rayleigh fading channels
A numerical method has recently been presented to determine the noise thresholds of low density parity-check (LDPC) codes that employ the message passing decoding algorithm on the additive white Gaussian noise (AWGN) channel. In this paper, we extend this technique to the uncorrelated flat Rayleigh fading channel. Using a nonlinear code optimization technique, we optimized irregular LDPC codes ...
