METHOD OF TRANSMITTING AND RECEIVING INFORMATION USING FREQUENCY-SHIFT KEYED SIGNALS Russian patent published in 2024 - IPC H04L27/32 H04L5/00 

FIELD: radio engineering.

SUBSTANCE: invention is intended for transmitting discrete information in radio communication systems. In the method of transmitting and receiving information using frequency-shift keyed signals, a uniform binary code is selected to encode subcarrier frequencies, the number of elements of which strictly corresponds to the number of subcarrier frequencies available for transmission. Moreover, from all available combinations of a uniform binary code, combinations in which only one information zeros are present, and combinations in which only one information units are present are excluded. As the calculated value, the result of averaging the sums of the maximum and minimum values selected among the calculated average values of the power of the spectral components within each of the subcarrier frequencies is determined.

EFFECT: increased transmission speed in a channel with a limited frequency resource.
