METHOD OF DISCRETE BINARY INFORMATION TRANSMISSION BY PHASE-MODULATED SIGNALS IN MULTI-CHANNEL RADIOCOMMUNIC SYSTEMS WITH FREQUENCY SEALING OF PHASE-MODULATED CHANNELS SUBCARRIERS Russian patent published in 2018 - IPC H03D3/00 H04L27/14 

FIELD: radio engineering, communication.

SUBSTANCE: method for transmitting discrete information comprises the steps of transmitting and phase demodulating the channel subcarriers. In transmission, all channel subcarriers are formed in the audio frequency spectrum from the lowest frequency subcarrier from the highly stable sound generator. Each of the channel subcarriers is obtained by doubling the frequency and phase of the adjacent lower frequency channel subcarrier that is phase modulated by binary sends from its channel message sources, separated by channel filters and demodulated in its channel phase coherent demodulator by multiplying with its channel phase reference that is obtained by doubling the frequency and the phase of the adjacent channel phase modulated subcarrier of lower frequency, obtaining the transmitted channel binary messages without the relative decoding and reverse operation.

EFFECT: increase of noise immunity and simplification of multi-channel radio communication systems by eliminating the inherent phase modulation of arbitrary change of polarity of parcels at reception.
