Shefer O. Models and methods of increasing the quality of functioning of onboard radio local systems

The object of the research is a process of adaptive compensation of non-linear distortions of the radio signal. The purpose of this dissertation is to increase the quality of functioning of onboard radio local systems. Methods of theory of signals and systems, theory of aimed evaluation of parameters and conditions and theory of finding out the signals, apparatus of theory of probabilities, a functional method of Volterra series, a method of theory of noise immunity and methods of finding out and adaptive processing of signals were used. Practical results were obtained with the help of using the methods of imitative modeling, calculating mathematics and taking up decisions. This dissertation id devoted to resolving an actual scientifically-technical problem of theoretical grounding and developing a methodology of increasing the quality of functioning of onboard radio local systems on the basis of creating the adaptive methods of compensation of non-linear distortions and the synthesis of non-linear adaptive compensators. The usage of created methodology allows assuring the reservoir of onboard radio local systems for the noise immunity up to (8-10) %, and the utilization of non-linear adaptive compensators allows obtaining the necessary values of parameters and the way of connecting the radio devices that allow increasing the reliability of functioning of telecommunication systems up to (6-12) %. A branch of science – technical.
