The objects of research are devices for determination of parameters and descriptions of radio channels. The article of research describes indexes and descriptions of functioning of devices and channels of informative radio networks and systems. A purpose of work are development and research of methods of receipt of reliable information of radio channels separate descriptions with parameters which occasionally change which include functions of dispersion and function of spectrum of the temporal stoppings beating on separate frequencies for making of ideology of methods of receipt of information regardless of provided quality. According to the research work mathematical correlations are shown out for the reflection of informative and tester signals and their spectrums on the output of channel with occasionally changing parameters, correlations for a calculation and analysis of the synthesized complex signals and complex rounding informative signal. The method of research of spectrum of stoppings beatingis developed with registration of squaring constituents of informative signal and expedience of his practical application is set also; the model of channel is developed with the eventual number of ways of distribution, which allow to conduct the analysis of decision of optimum reception of signals, passed on a channel with parameters which occasionally change ; set and probed terms at which possibility of establishment of maximally plausible estimations of measurings is got in radio channels. An application domain is the systems of telecommunications.
