We consider the problem of frequency estimation of the periodic signal multiplied by a Gaussian process (Ornstein-Uhlenbeck) and observed in the presence of the white Gaussian noise. We demonstrate the consistency and asymptotic normality of the maxi

We find a new expression for the solving statistics of fast fluctuating Gaussian pulses with arbitrary-function envelope, based on which we can receive much simpler processing algorithms of random signals with unknown parameters in comparison with av

Restoration algorithms of signals and images on the basis of their generalized spectra in bases of orthogonal polynomials and functions at absence and presence of random distortions have been examined. It is shown that in absence of hindrances the nu

We consider the problem of the estimation of the position on the plane and of the moment of beginning of emission of a source by observations from K detectors on the plane. We propose the conditions of regularity and identifiability, which allow us t

The algorithm for detecting the coherent-pulse signals against correlated interferences is considered. It is invariant to both the carrier frequency of the signal and the statistical characteristics of its fluctuations. Its optimization is implemente

Analysis of the radio environment in a wide frequency band carried out by radio monitoring systems, including correlation-interferometric direction finders, involves, among other things, the detection of the frequencyhopping spread spectrum signals a

The generalized maximum likelihood algorithm is introduced for detecting the abrupt change in the band center of a fast-fluctuating Gaussian random process with the uniform spectral density. This algorithm has a simpler structure than the ones obtain

In this paper, the quasi-optimal and optimal algorithms are considered for discriminating the pulse signals by arrival time in the presence of the fast Gaussian modulating interference and additive Gaussian white noise. The case is examined when the
