Performances of the Decoding Algorithms near Shannon Limit

Abstract

Forward error correction technique based on the optimization procedures for multithreshold decoding algorithms is considered. Recent advances as well as new opportunities of the multithreshold decoders for use in the systems working at the Shannon’s limit are analysed. Performances of the multithreshold decoders for self-orthogonal binary and non-binary codes over Gaussian channels are presented. Simulation results of BER performance of proposed decoder is shown to be close to the results provided by optimum total search methods.
