The methodology of teaching the basics of modeling physical processes in the equipment of the radio communication channel

A modern specialist in the technical operation of transport radio equipment must have theoretical knowledge, practical skills and abilities to develop the structure of the object of professional activity, select the parameters of equipment for technical diagnostics and its possible modernization. Therefore, within the framework of the educational process, complex methods of studying radio-electronic means based on individual objects of professional activity are used.

At the Department of Radio Electronics, one of the basic objects studied is the equipment of the ship's radio communication channel. The study of physical processes in a communication channel begins with the study of analog systems in junior courses. The aim is a theoretical study of classical methods of converting radio signals by linear and nonlinear radio circuits in transmitting and receiving devices. The visibility of transformations in order to form a holistic vision of the structure and functions of individual blocks and all communication channel equipment is provided by computer modeling in the Multisim software environment.

In senior courses, the object of research is digital radio-electronic devices that provide signal conversion in digital radio communication channels. Special attention in the learning process is paid to the relationship between analog and digital radio electronic devices; the features of sampling analog signals, synthesizing linear digital filters, and digital detection are clarified. Theoretical research is supported by computer modeling of the digital communication channel in Matlab Simulink, which allows analyzing the entire path of conversion of the low-frequency control signal by the receiving and transmitting equipment.

The introduction of this research methodology, which includes both theoretical study and computer modeling of processes in analog and digital radio engineering systems, into the educational process will increase the quality and effectiveness of the formation of professional competencies among future graduates of the specialty "Technical operation of transport radio equipment", increase their competitiveness in the labor market.
