METHOD OF TRANSMITTING INFORMATION USING BROADBAND SIGNALS Russian patent published in 2020 - IPC H04L27/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering and specifically to transmission of discrete information by broadband wireless communication systems. Proposed method comprises generation on the transmitting side of a frequency-modulated Doppler-invariant signal, use thereof as a carrier wave, encoding each transmitted alphabet symbol a_i, individual time shift τ of the carrier oscillation argument origin, transmitting the modulated signal through the communication line. At the receiving side, the energy sums of the cross-correlation functions Y(τ) of the input signal with quadrature standards of frequency-modulated signals with given parameters and different time shifts τ_i origin of carrier oscillation signals. Received symbol is assigned the value a_i, for which the found energy sum of the cross-correlation signal processing Y(τ_i) turned out to be maximum.

EFFECT: invention is intended to increase noise immunity by providing a high level of signal/noise ratio.
