Despite the active use of channel division technology, Russian manufacturers of switching equipment depend on foreign suppliers of components. Therefore, the task arises of developing simple schemes of switching devices and completely abandoning foreign materials, thereby solving the problem of import substitution.

Goal – reducing the complexity of code channel division schemes through the use of the developed channel division method using convolutional coding.

A method for channel division using convolutional coding has been developed. For comparison, a description of channel separation using block coding is provided. The method for specifying convolutional codes for channel separation is similar to the method for specifying block codes, but has some features. It is shown that elements from the field of formal Laurent power series with coefficients from a certain finite field are used as components of the transmitted message and code word. The possibility and conditions for error correction simultaneously with code division of channels are considered.

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.
