The article proposes new methods for code-division multiplexing of communication channels and a comparative assessment of spectral efficiency of the proposed methods with the known methods. The analysis of channel multiplexing methods for communication systems is carried out and the possibilities of increasing the interference immunity and security of the signal structure under the operation conditions of communication systems in a busy frequency range are considered.
