In this paper, the authors present results of the studies aimed at development of new method for formation of signals for cognitive radio communication systems, which would allow increasing spectral efficiency of systems for data transmission as compared to the existing approaches. Signals which are used in cognitive radio communication systems now-a-days (signals with Orthogonal Frequency Division Multiplex (OFDM)) have a number of disadvantages, one of which is high level of side lobe of some subcarrier, and that fact doesn't allow providing potential spectral efficiency of cognitive radio communication system.
