Formulation of the problem. At present, there is a need to develop a switching equipment that would provide fast and high-quality connection of devices and subscribers, as well as comply with modern standards for switching digital transmission channels.

Goal. Reducing the complexity of code channel division schemes through the use of the developed method for synthesizing encoding matrices based on polynomials.

Results. The method of the synthesis of circulant polynomial matrices for the implementation of the operation of code combining of channels on the transmitting side of the communication system has been developed.

Practical significance. The research results can be applied in communication systems with multiple access, with a wide coverage area, high quality of data transmission, high noise immunity, stability of communication channels from interception and eavesdropping.
