Abstract:
The issues are considered that are associated with mathematical modeling of the probability density function of instantaneous values of the signal and additive noise in the presence of multiplicative (modulating) noise. It is shown that if the law of phase distribution in the interval (0, 2π) differs from uniform distribution, then in this case, the signal is a non-stationary random function that tends to stationary with an increase of phase distortion.
