SYNDROME DECODING METHOD OF DECODING UNSYSTEMATICAL CONVOLUTIONAL CODE (VERSIONS)

FIELD: information technology. ^ SUBSTANCE: for the received distorted coded implementation, a syndrome sequence is calculated, in which localised syndromes are determined, and, using an iterative procedure for presenting the localised syndrome in form of linear combinations of syndromes with single errors, the group of localised units of minimum weight errors is determined during decoding with "solid" solution, while during decoding with "soft" solution, the group of localised units of errors with maximum metric is selected. ^ EFFECT: increased authenticity of decoding, reduced device and computational complexity and faster operation of the decoder during optimum decoding procedure. ^ 2 cl, 1 dwg
