METHOD FOR NOISE-PROOF TRANSMISSION AND RECEPTION OF INFORMATION BASED ON FREQUENCY-SHIFT KEYED SIGNALS Russian patent published in 2022 - IPC H04L27/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and can be used in radio electronic systems (RES), including radio communication systems. To achieve the effect, the method selects a list of operating frequencies, the number of which is determined as the result of the product of the number of subcarriers required to transmit one information block and the number of combinations of the selected code with a constant weight that will be used for message transmission. The specified frequency range is divided into frequency intervals in such a way that in each frequency interval the number of operating frequencies corresponds to the bit width of the code with a constant weight, which determines one transmitted information block. Each frequency interval is assigned a unique available code combination with a constant weight.

EFFECT: increasing the noise immunity of transmission and reception of signals under the influence of radio emissions from third-party RES, localized in the signal reception band.
