METHOD FOR ENCODING AND TRANSMITTING DIGITAL INFORMATION Russian patent published in 2021 - IPC H03M13/00 H04B1/00 

FIELD: wireless communication.

SUBSTANCE: invention relates to wireless communication systems. A method is proposed, which consists in the fact that digital signals are emitted in the form of radio waves through an antenna unit, one antenna. In this case, the signals from the digital signal source are sent to the control unit, and then to a number of keys, the second inputs of which are supplied with one of the “n” frequencies created by the synthesizer. The number of keys and frequencies is the same. Then the frequencies that have passed through the public keys are sent to the adder, from the output of which they are sent to the antenna and radiated into the ether. Those keys that do not receive control signals from the control unit remain closed, and the corresponding frequencies, respectively, do not arrive at the adder and are not radiated to the ether. The set of frequencies emitted at the moment corresponds to the transmitted digital signal.

EFFECT: increase in the efficiency of the method for expanding the alphabet of code messages while simplifying the design of the antenna unit.
