Abstract

The issues related to signal processing in radio-technical systems are considered in the paper. The elements of the radio-technical systems, in particular driving oscillators, do not provide the ideal stability and consistency of parameters with time that causes nonstationarity of processed signals and leads to the losses in the signal-to-noise ratio with respect to the calculated values. As a result of these losses, the performance characteristics of radio-technical systems are degraded. It is important to estimate the value of resulting losses and to consider possible methods of their reduction. The main purpose of the research is to analyze energy losses of the signal at its accumulation in the receiving device of the radio-technical system. The simulation modeling method and statistical processing of results were used during the research. The research results can be used in the development and modernization of the radio-technical systems of information transmission and extraction, in particular long-haul systems.
