Formulation of the problem. The volume of information that needs to be transmitted over switched communication channels doubles every year, and therefore there is a need for switching equipment that would provide fast and high-quality connections to subscribers.

The technical implementation of such switching devices requires large production costs. The task arises of developing and researching switching devices built on simpler schemes.

Goal. Reduce the complexity of encoding and decoding devices in communication systems with channels’ division.

Results. The synthesis method of encoding and decoding matrices is proposed for implementing a code division of channels regardless of the number of users. The synthesis and implementation of theses pairs of matrices will significantly simplify the schemes for constructing encoding and decoding devices. The simplicity of these schemes allows us to hope for the widespread implementation of such devices on many communication lines.

Practical significance. The research results can be used to ensure reliable information transmission in various communication technologies, in real-time systems, in distributed systems and on-board equipment complexes.
