The demodulation signal under the influence of additive and multiplicative non-Gaussian noise

Abstract

The issues of quasi-optimal signal processing in conditions of simultaneous effect of additive and multiplicative non-Gaussian noise are considered. It is shown that with given a priori information about probability density function of the multiplicative noise, the accuracy of the measurement of the information parameter of the signal, in the case of its slow fluctuations can be significantly worse than in the case of rapid fluctuations of multiplicative noise.
