FIELD: wireless communication equipment.
SUBSTANCE: invention relates to communication engineering and can be used to generate and process a signal based on an orthogonal basis of eigen vectors of a subband matrix. To achieve the technical result, a signal with channel compaction is generated from the transmitted information based on the orthogonal basis of the eigen vectors of the subband matrix, calculated for a given frequency band or a set of frequency bands in a given frequency band. On the receiving side, reliable information recovery from the received signal is enabled. In the receiving/transmitting equipment any modifications can be used before and after the orthogonal compaction based on the eigen vectors of the subband matrix, aimed at improvement of transmission speed, reliability, noise immunity, efficiency, reduced level of power consumption, increased speed of calculation and other parameters.
EFFECT: low level of out-of-band radiation of communication signals.
