Currently, in Russia, as well as throughout the world, there is a significant increase in the demand and importance of information technology. The volume of information transmitted via switched communication channels, including space and satellite, is greatly increasing. Therefore, the task arises of developing switching device schemes with a smaller number of mathematical operations compared to analogues.

Goal – Develop principles for constructing schemes for implementing code channel combining on the transmitting side and code channel division on the receiving side of the communication system.

Based on an analytical review of modern scientific, technical, regulatory, methodological literature on switching methods and descriptions of mathematical models of signals, a study of the principles of switching using code channel division was carried out and proposals were developed for the synthesis of orthogonal encoding and decoding matrices, with the help of which channel division is possible using simple schemes.

The research results can be applied in space and satellite communications technologies, in real-time systems, in distributed systems in on-board equipment complexes, to ensure reliable information transmission.
