FIELD: radio engineering and communications.SUBSTANCE: invention relates to radio communication and can be used for transmitting confidential information over radio communication channels with limited frequency resource. Method of generating and processing a signal built in a masking interference involves formation of a useful signal and a masking interference at the transmitting side in the same transmitting device as an additive mixture, selecting the carrier frequency so, that the signal spectrum is within the bandwidth occupied by the masking interference, as well as selection of such structure of the masking interference, that its spectral components at frequency positions occupied by the useful signal are absent or the modulus of their amplitude does not exceed 5 % of the modulus of amplitude of spectral components of the useful signal, and on the other frequency positions, not occupied with the useful signal, the amplitude of spectral components of the masking interference in magnitude is equal to the amplitude of spectral components of the useful signal.EFFECT: method of generating and processing a signal built in a masking interference implemented by one radio transmitter.1 cl, 5 dwg |
