The use of differential transformations in modeling of communication systems

Abstract

An important problem is the development of systems whose structure and composition are based on new principles of signal processing. A method of modeling communication systems on the basis of differential spectrum transformations (see Pukhov G.E., 1986) is offered. The purpose of this work is the development of the theory of differential transformations and to develop on this basis the methodology of optimization and discretization of systems. The new approaches to modeling, connected with discretization on the basis of differential transformation and subsequent processing of differential spectrum are offered in the research. Our investigations show the principle possibility of improvement of the communication system technical characteristics and, in particular, systems with a distributed spectrum as a result of optimization by means of the differential transformations of signals. An experimental mock-up of the delta-pulsing communication system from ready functional units was created. It took the form of a microwave link in an urban environment. Audibility of the accepted speech signal was wholly sufficient for understanding a message.
