Abstract

Background. At present, the demand for broadband signals (BВS) is determined by the qualities inherent in these signals, which make it possible to ensure high noise immunity of broadband communication systems (BСS) when transmitting confidential information in an open radio channel, especially in emergency situations. Although the foundations of the BВS theory are well known, the development of wireless communication networks requires constant refinements of theoretical provisions in accordance with new data on methods for constructing Barker code sequences used in wireless communication
systems with direct sequence spread spectrum technology.
Objective. The aim of the paper is to study new composite Barker codes as synchronization signals and compare them with known composite codes using simulation.
Methods. Analytical methods of calculation are used, as well as simulation modeling in the MatLab software package.
Results. Simulation modeling was carried out, which confirmed the possibility of using new composite Barker codes as synchronization signals in the BCS.
Conclusions. Modeling in the MatLab software package showed a greater noise immunity of new composite codes to the influence of various modulating sequences of an information signal in comparison with known composite codes.
