METHODS FOR GENERATING NOISE-LIKE TIMER SIGNALS BASED ON PSEUDO-RANDOM TUNING OF THE OPERATING FREQUENCY

Abstract

Among the most important scientific problems, which have been given much attention recently, is the research of the properties and methods of forming complex noise-like signals to increase the interference protection of radio communication systems, operating in the conditions of electronic conflict. Such signals have inherent properties that help solve problems of improving noise immunity, secrecy transmission and providing electromagnetic compatibility of various radio communication systems. For the synthesis task of noise-like signals, it is proposed to use timer signal constructions in combination with various methods of spectrum expansion based on random restructuring of the operating frequency. The expediency of using timer signals is justified by their properties which increase the noise immunity and secrecy of transmission. However, unlike the position codes, they have a more difficult structure for constructing signal constructions. The primary parameters for constructing timer signals allow the formation of the various sets of signal constructions. Such variational possibilities of constructing timer signals substantially increase the potential structural secrecy of the transmission. Also, based on timer signals, noise-immunity coding is implemented without additional test elements. In the article was carried out the analyses of methods synthesis based on random rebuild operating frequency, taking into account the non-positional timer signals.
