OPTIMAL SYNDROME DECODING OF TURBO CODES WITH COMPONENT SYSTEMATIC RECURSIVE CONVOLUTIONAL CODES

RESUMO

An analysis expression for computation of a syndrome sequence of a systematic recursive convolutional code has been produced. A method for decomposition of localized syndromes for determining distorted elements in a code sequence of a turbo code, which makes it possible to develop an approach to synthesis of optimal syndrome decoders both with a "hard" and "soft" solution of turbo codes with component systematic recursive convolutional codes, has been proposed.
