METHOD FOR GENERATING AND PROCESSING SIGNAL EMBEDDED IN MASKING INTERFERENCE Russian patent published in 2024 - IPC H04K3/00 H04K1/02 

FIELD: radio communications.

SUBSTANCE: invention can be used to transmit confidential information over radio communication channels with a limited frequency resource. The method of generating and processing a signal built into masking interference additionally consists in the fact that for each change in the value of the carrier frequency of the useful signal, a different value of the symbolic signal transmission rate is set, and with each change in the value of the carrier frequency of the useful signal, the value of the symbolic transmission frequency of the signal and the structure of the masking interference are changed for each value of the carrier frequency of the useful signal is selected taking into account the fact that each change in the symbol transmission rate of the signal leads to a change in the width of the frequency spectrum band it occupies; when isolating a signal at each carrier frequency, the change in the structure of the masking interference is taken into account, taking into account the fact that each change in the symbol rate signal transmission leads to a change in the width of the frequency spectrum band it occupies. Changes in the symbol rate of the signal are known at the receiving end.

EFFECT: improved confidentiality of information due to changing the bandwidth of the information signal built into the structure of the masking interference.
