Method of Parametric Synthesis of Systems for Providing Electromagnetic Access for Radio Monitoring Facilities of Radio Emission Sources with Quadrate Amplitude Modulation of Satellite Communication Systems

The purpose of research development of a method for parametric synthesis of systems for providing electromagnetic access by means of radio monitoring of radio emission sources with quadrature amplitude modulation of various positioning of satellite communication systems.

Methods. Probability theory, mathematical statistics, statistical radio engineering and computational mathematics were used in conducting research and developing a method for synthesizing an electromagnetic access system. Signal constellations with quadrature amplitude modulation with positivity L no more than 256 and nonuniformity X = 1 are considered as accepted assumptions. This decision is justified by their use in modern and promising satellite radio systems for information transmission. In the paper, all the results of the probability of reliability of the received data by means of radio monitoring are reflected for the case of rigid decision-making.

Results. Mathematical models of the dependence of equivalent energy losses in structural and functional nodes on destabilizing factors have been developed for a given probability of reliability of receiving signals with quadrature amplitude modulation on the symbol; an integral assessment of the quality of radio monitoring of fixed and mobile satellite communication lines has been determined; the cost of creating such radio engineering paths as antenna-feeder on domestic and foreign bases has been estimated., receiving-selecting, demodulating; A procedure has been developed for parametric synthesis of systems for providing electromagnetic access of radio monitoring facilities to the resources of satellite communication lines, taking into account the efficiency indicators of providing electromagnetic access.

Conclusion. The scientific work presents a method of parametric synthesis of systems for providing electromagnetic access to radio monitoring means of digital satellite communication lines with complex types of modulation, which differs from the known ones by taking into account energy losses in structural and functional units previously neglected due to their low influence associated with low data exchange rates.
