Abstract

A method of improving the performance of non-binary redundant code decoders in a coherent network system using forward error correction is considered. It is proposed to use permutation decoding which in contrast to the known methods of processing error-correcting codes has a number of deterministic parameters. Such parameters in the procedure of decoding code vectors can be determined in advance and included in the cognitive map of the decoder. The using of cognitive map data dramatically reduces the amount of matrix calculations in the permutation decoding of system, which contributes to the performance of the decoder. This contributes to the harmonization of high-speed data flow to the input of the decoder of the optical system on the physical level with relatively limited processing capabilities of the processors on the data link layer. The methods of reducing the memory size of the cognitive map of such decoder and fast search of reference matrices of equivalent codes through the use of lexicographic navigation are considered.
