Імітаційна модель передавання текстових і аудіо повідомлень з викориcтанням нероздільного факторіального кодування в середовищі Simulink

Abstract

The work is devoted to the development of a model for text and audio messages transmission using non-separable factorial coding. The creation of a simulation model using Matlab and Simulink software products and the process of setting their parameters are considered. The algorithm for encoding text messages and the algorithm for encoding samples of an audio signal are given. The resulting model makes it possible to investigate probabilistic indicators of the information exchange process as well as assess the impact of communication channel error on the quality of various types of messages (text or audio) reproduction. The use of the developed model is also necessary to create mock-up samples of secure information exchange devices based on non-separable factorial data coding.
