The approaches for spectral efficiency improving in the data transmission are analyzed. The ways for the improvement of the noise immunity of radio channels are presented. During the analysis, signal parameters have been found, which are necessary for obtaining intelligence information by opposition. The method of forming a signal-code design of radio channels with high characteristics has been proposed. A mathematical formulation of the problem of searching for the type of signal-code design, which is optimal for the criterion of increasing the data transfer speed has been carried out. It has been shown that the use of orthogonal nonlinear code sequences with multidimensional modulation of signals allows not only to increase the efficiency of communicating information, but also preserves the specified requirements for the quality of the radio channel.
