摘要：The examined a technique for estimating the interference immunity of a communication and control system at the physical level using signal-code structures. Mathematical expressions are obtained,which allow estimating the noise immunity of communication and control systems during the interconnection of an information signal and structural interference. Probable characteristics are analyzed with the use of frequency-phase-manipulated signals and cyclic codes. Dependence’s of noise immunity of communication and control systems in the interaction of an informative signal and structural interference are presented. The most promising are orthogonal signals and methods of encoding multi-core encoding;at the same time,the literature does not have a method for analyzing the impedance of communication systems and control systems,and no analysis of such systems has been performed using the dynamic mode of the system's operation. In order to maintain the useful properties of the class of signals used and to provide them with sufficient protection against the optimal intended damage,it is necessary to prevent the interference provider from agreeing the structure of the interference with the signal. Analyze interference-protected communication and control systems with the consistent use of signal-code designs. The research has shown that the quality of communication and control systems depends on the class of signals used and the algorithms for constructing unprotected codes. The most promising are orthogonal signals and methods of encoding multi-core encoding;at the same time,the literature does not have a method for analyzing the impedance of communication systems and control systems,and no analysis of such systems has been performed using the dynamic mode of the system's operation. It is necessary to take into account the joint application in the radio channel with parameters that are measured,orthogonal PFM signals and noise immunity codes,to conduct research to select and justify the parameters of the signal-code design. Full optimization of the necessary parameters of the radio channel with the use of this mathematical device can not be achieved,because it is necessary to take into account other indicators of the quality of the operation of the radio channel.
