OPTIMAL SYNDROME DECODING OF CONCATENATED CODES WITH SERIAL CONCATENATION VIA AN INTERLEAVER OF CYCLIC LINEAR BLOCK-STRUCTURED CODES

摘要

The process of selection of an optimal vector for adjusting the code word in a concatenated code from alternative groups of localized strings of errors, shaped on the basis of an extended syndrome of component codes in the form of linear combinations of extended check matrix' rows, is proposed. This is required to develop an approach to synthesis of optimal syndrome decoders with "hard" and "soft" solutions of concatenated codes with a serial concatenation via an inter-leaver of cyclic linear block-structured codes.
