Sayko V. Methods and means of improving the efficiency of functioning networks of digital radio on multipath channels.

Object - high-speed network systems and mobile radio communication; the purpose of the thesis is to develop theoretical foundations of optimization of structures and parameters of systems and networks, digital radio future generations, building on the basis of methods and algorithms to enhance the functioning of such networks and practical implementation of these methods and algorithms for high-speed transfer of information on multibeam channels, theoretical and practical results, novelty - The estimation of noise immunity modes of radio communication systems with orthogonal pidnesuchymy and a comparative analysis of the effectiveness of modern practical algorithms for adaptive disconnected pidnesuchyh OFDM-systems; improved statistical method of frequency adaptive radio communication for professional radio with accessible channels and a method of adaptive distribution pidnesuchyh subchannels in OFDM-system taking into account the depth of fading signal, developed and studied noise stability means of communication over wireless mobile radio systems in the new generation; branch of Service - engineering, telecommunications.
