Simulation of the Influence of Non - Gaussian Noise During Measurement

Abstract

The mathematical model of the influence of non-Gaussian interference has been developed and a nonlinear method of non-Gaussian interference in signal acquisition and information processing by measuring means based on asymptotically optimal reception has been developed. According to the criterion of maximum likelihood in the asymptotic approximation, it was found that the main node of the receiver of the decision device, which provides the maximum, but possible attenuation of strong non-Gaussian interference, is a nonlinear inertial converter, the amplitude characteristic of which is uniquely determined by interference. Analysis of the characteristics showed a strong suppression of interference with the optimal characteristics of the block of non-Gaussian interference and quite large - when using a limiter with a positive excess of the distribution.
