FIELD: information technologies. ^ SUBSTANCE: method of adaptive information interleaving in communication channels with errors grouping consists in the fact that noise-immune code word symbols are interleaved on the transmitting side, and an information package made of noise-immune code word symbols is sent into a communication channel, on the receiving side the received information package symbols are de-interleaved, and words of noise-immune code are produced, using results of noise-immune code words decoding, distribution is assessed in probabilities of error packages length with different multiplication factors, the integral distribution of error package length probabilities is produced, and the initial value of interleaving depth is determined, which is equal to the length of error package, the integral distribution of length probabilities of which exceeds the specified probability of message delivery. Then distribution of error probabilities is compared in words of noise-immune code with distribution of error probabilities of a binomial distribution law, and depending on comparison results, correction of interleaving depth value is carried out, which is then delivered to the transmitting side along the feedback channel. ^ EFFECT: increased accuracy in determination of the interleaving depth value in non-stationary communication channels with errors grouping. ^ 4 cl |
