Results of long-term researches in the field of multithreshold decoding (MTDs) of self-orthogonal codes development are presented. Bases of multithreshold decoding are stated, possibilities of MTDs implementation on modern element base are shown. The performance comparison of MTDs and concatenated methods of error correction based on them with decoders of the best error-correction codes over the binary Gaussian channel, the q-ary symmetric channel and the erasure channel is fulfilled. It is shown the MTDs provide efficiency comparable to other error-correction methods at significantly smaller implementation complexity.
Key words: communication system, error-correction coding, self-orthogonal codes, multithreshold decoder, concatenated codes, decoder complexity, binary Gaussian channel, q-ary symmetric channel, erasure channel.
