Formulation of the problem. Currently, the desire for the development of code-division access technology is explained by an increase in subscriber density, resistance to interference, as well as a high degree of protection of transmitted data from unauthorized access.

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

Results. The application of a previously developed method for synthesizing circulant polynomial matrices to implement code channel separation is considered. The structure of the synthesized matrices is the basis for reducing the complexity of encoding schemes and, consequently, the radiated power of radio transmitters of subscriber devices. The limitation of the application of the method and its use under the conditions of this limitation are considered.

Practical significance. The developed method 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.
