The issue of improving the efficiency of radiocommunication systems and radiocommunication complexes in a complex radio-electronic environment is a prime scientific problem, which attracts attention of a large number of leading scientists. In this article, the author carried out research aimed at increasing the structural secrecy in radio-frequency communication systems with orthogonal frequency multiplexing using timer signal constructions, due to the development of a method of increasing the secrecy in radio-frequency systems with orthogonal frequency muxification due to the use of timer signal structures. In the course of the research carried out by the author, the basic provisions of the theory of communication, the theory of impedance protection, the theory of complex technical systems, the theory of antagonistic systems, the theory of noise immunity coding, the theory of chaotic processes, the theory of orthogonal systems, the theory of radio frequency planning and the theory of timer signal structures. The difference in the proposed methodology from the known, which determines its novelty are: the use of timer signal structures, in contrast to the traditional position signaling structures, it can increase the structural secrecy of signals with orthogonal frequency multiplexing; the use of expanding sequences of different types and with different autocorrelation properties allows for the operational adaptation of parameters of systems and radio communication equipment with orthogonal frequency multiplexing to the effect of destabilizing factors aimed at disclosing the properties of systems and radio communication equipment for electronic intelligence; application of the mechanisms of frequency adaptation to the effect of intentional obstacles allows you to determine the areas of the frequency range struck by them and conduct the intellectual planning of using the radio frequency resources by radio communication systems with orthogonal frequency multiplexing.
