Abstract
Proposals are presented on the use of signals generated on the basis of the three-element Barker sequence for the mode of frequency-hopping spread spectrum (FHSS). The conditions for the application of the frequency hopping mode are considered. An algorithm for synthesizing signals with a simultaneous change in their frequency and phase structure has been developed. An analysis of the properties of the developed signals was carried out. The positive and negative aspects of the implementation of the developed approach are shown. Proposals for their practical application are formulated. The frequency-hopping spread spectrum is actively used in many telecommunication standards and technologies in order to increase the noise immunity of transmissions in a multipath channel. As a result, due to the short stay of the signal at the carrier frequency, the probability of long-term operation in a channel with deep fading is reduced. Since the structure of the signal and frequency-hopping spread spectrum parameters are determined by known protocols and standards, this makes it possible to evaluate its capabilities in practical applications. In order to reduce the negative consequences caused by the considered collisions, it is proposed to generate signals for the slow frequency-hopping spread spectrum based on the three-element Barker sequence. Features of the implementation of this approach are considered in this article.
