MODELING COMMUNICATION SYSTEMS TO STUDY THE EFFECT OF INTERFERENCE IN THE TRANSMISSION MEDIUM

Abstract

Context. The problem of creating a model of transmission and transformation of information has been resolved, the processes of information transformation in transmitters and receivers have been considered, the process of influence of the destabilizing factors in the communication channel has been investigated. Objective. The study aims to create a mathematical model of the communication channel, taking into account the destabilizing factors that affect the transmission channel and control the correctness of the communication channel model. Method. A mathematical model, which evaluates the stability of the signal in the communication channel at the stage of designing telecommunication systems for various purposes, taking into account the effects of destabilizing factors in the environment of information signal transmission, is proposed. It is also a proposed method of determining the parameters of information signals in the communication channel and the increase in the bandwidth during exposure of external destabilizing factors on the signal transmission medium in the communication channel. Results. A mathematical model of the communication channel was obtained, which takes into account external destabilizing factors that can affect the communication channel and equipment. The developed model contains a method of verification, which allows determining its correctness. Conclusions. The method of information transfer has been improved by adding a verification method. The value of the bit error obtained during the simulation of the communication channel coincides with the value of the bit error during the verification process, which indicates the correctness of the considered mathematical model of the communication channel. The modeling of the communication channel confirmed the adequacy of the proposed method of modeling the communication system, so this method can be recommended for use in the design and research of telecommunications systems.
