FIELD: information technologies.
SUBSTANCE: convolution interleaver for processing of code word produced from input unit of symbols with usage of coding with addition of excess and containing more symbols than input unit, besides, code word contains a sequence of interleaving units, and each interleaving unit contains at least two symbols and includes an interleaving facility. Interleaving facility changes sequence of interleaving units to produce interleaved code word, containing varied sequence of interleaving units. In particular, interleaving facility does not vary sequence of symbols inside interleaving unit. However, sequence of interleaving units relative to each other or relative to previous or subsequent code word, varies.
EFFECT: reduced probability of transfer errors.
