INVESTIGATION OF MULTIDIMENSIONAL ANALYTICAL MODEL OF SOURCE OF NOISE IN DISCRETE COMMUNICATION CHANNELS

Abstract

The method of checking the adequacy of the stochastic models of noise sources in binary discrete communication channels is suggested. The technique is based on a comparison of the theoretical probability characteristics of a discrete channel and corresponding statistical estimates of these characteristics. Bit error probability, average error-free interval length and probability of receiving a block of a certain length with errors and errors with fixed multiplicity were chosen as main indexes of estimated characteristics. The calculations for the four-dimensional model were performed. The ratios of theoretical and statistical estimates of the discrete channel parameters were determined.
