Purpose of the study is to build new mathematical models and methods for optimizing data transfer modes in multi-channel transmission systems to increase their bandwidth and expand the frequency range of transmission.Research methods the theory of propagation of electromagnetic waves, theory of discrete orthogonal transformations, methods of digital data processing in localized spectral bases, theory of teletraffic.Following methods developed: determination of traffic of infocommunication networks with fractal teletraff, optimal according to the criteria for optimizing the bandwidth of data transmission channels;determination of spatial positioning of radiating devices of wireless nfocommunication networks, optimized according to criterion of minimizing energy losses of communication signals. Multi-criteria model of ompression of signals in wireless infocommunication networks with partial loss of information has been developed, optimized according to the criteria for minimizing energy losses and information significance. Recommendations on the choice of algorithmic base compression of signals according to energy and information criteria are given. Methods for optimizing data transmission traffic in wireless multi-server telecommunication networks with failures and with various options for organizing transactional queues according to the criteria for maximizing error-free data transmission have been developed.Result of the research, a new algorithmic base for optimizing the transmission of transactions in infocommunication networks according to the criteria for minimizing energy losses of signals and time characteristics of transmission with a controlled level of information preservation has been developed. Scope of use: for compression of broadband signals in space communication systems, design of wireless communication systems of the terahertz range.
