METHOD OF DECODING TURBO-CODE (VERSIONS)

FIELD: information technology. ^ SUBSTANCE: for the received distorted code implementation of a turbo-code with recursive convolutional code components, syndrome sequences are calculated for each code component. After that localised syndromes are determined, and, using a procedure for generating a secondary class of error vectors, the error vector with minimum weight (metric) is determined during decoding with a "solid" solution, and during decoding with a "soft" solution, an error vector with the maximum modified metric (most probable error) is selected. ^ EFFECT: increase authenticity of decoding, reduced device and computational complexity and realisation of an optimum decoding procedure. ^ 2 cl, 1 dwg
