Uryvs'kyj L. Fundamentals of the applied information theory for telecommunications.

The principle object of the investigation is to formulate the methodological principles and to develop the methods that will allow the application of information theory propositions to construction and analysis problems in telecommunication systems. In the current work the methodological principles are formulated with regard to construction and analysis problems in telecommunication systems. Taking into account the modulation type and the procedure of coding and signal processing the mechanism of capacity change depending on spatial-energy parameters of communication channel was established. The estimation methods for channel information capabilities are suggested for the problems of channel parameters analysis and synthesis on the basis of quantitative measure of information. By using the binary and multiposition signals the extremums in the dependence of the discrete communication channels capacity from its energy potential were revealed. Tacking into account the dual (discrete - continuous) nature of digital channel models the synthesis of their models as well the analysis of information capabilities in the case of discrete and continuous information sources for these channels were performed. The mathematical tool for generalization of “propagation and destruction” process for systems with “access conflict” was suggested. On the basis of quantitative measure of information the criteria and factors of the integral estimation of information capabilities for telecommunication channels were developed.
