Odiianenko E. Increased noise immunity and safety of telecommunication systems by applying techniques of spatial signal processing

Object of research: the formation and processing of signals with multithreaded transfer information. Objective: To improve noise immunity and safety of telecommunication systems by selecting reasonable values of the parameters of MDT, depending on the state of the communication channel. Methods: In solving the tasks of the thesis was used methods of the theory of signal theory of potential noise immunity, probability theory, matrix theory, optimization theory of mathematical modeling. For processing the results of experiments used the methods of mathematical statistics. Theoretical and practical results and novelty: first obtained the equations for radio system based on MDT under the action of continuous and impulse noise and selective fading, which allows reasonable choice of parameters, and determine the measures to combat various types of noise. The method of monitoring the state of the communication channel based on MDT interference and fading that can significantly improve the accuracy of estimates of the channel due to the low signal-to-noise ratio in comparison with known methods. For the first time the technique and guidelines for choosing the rational parameters values of MDT under the action of continuous and impulse noise and selective fading, which can get energy gain in noise immunity and reduce the number of channels. Degree of implementation: The results of the thesis have been used in research SE "Interdisciplinary Science and Technology Center Wind Energy" IVE NAS of Ukraine in the development of methods for evaluating the quality of radio communication systems and "Crypton-M" Ltd.
