Abstract

Statement of the problem. The analysis of the noise immunity of radio engineering systems (RES) for information transmission using phase-shifted signals with spread spectrum based on pseudo-random sequences involves examining their operation under conditions of structural interference, which can be stochastic and quasi-deterministic. The approach under consideration is intended for the analytical calculation of the noise immunity indicators of RES for information transmission under these conditions; it involves determining an equivalent signal-to-noise ratio that takes into account the combined effect of noise and structural interferences.

Objective. To present an approach to the analytical calculation of the noise immunity indicators of a radio transmission system transmitting information using spread-spectrum signals under conditions of stochastic and quasi-deterministic structural interference.

Results. Expressions have been obtained for the equivalent signal-to-noise ratio in a RES for information transmission under conditions of combined effects of noise and structural interference. The features of analyzing the noise immunity of a RES for information transmission under conditions of stochastic and quasi-deterministic structural interference are noted. The results of calculations of the stochastic structural interference parameter and estimates of the correlation coefficient with the signal of quasi-deterministic structural interference are presented; these parameters determine the degree of influence of structural interference on the reception of signals with spectrum expansion. A comparative analysis of the equivalent signal-to-noise ratio was carried out under fixed signal reception conditions in the presence of stochastic and quasi-deterministic structural interferences.

Practical significance. Analysis of the noise immunity of RES with spread-spectrum signals under various types of interferences is necessary for solving applied problems in the design of RES and means of their electronic suppression.
