COHERENT DIVERSITY SIGNAL TRANSMISSION METHOD Russian patent published in 2020 - IPC H04B7/05 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in radio communication systems. In the transmitting part of the first side, N diversity channels are formed, N signals are generated and assigning each diversity channel its signal, transmitting signals through the corresponding diversity channels, in the receiving part of the second side from the signals of the diversity channels after predistortion, by an inversion operation, an alphabet is made, from the elements of which the message is formed according to the rule stipulated by the parties, from the information source of the second side of the first, transmitting signals along diversity channels from the second side of the first, and in the receiving part of the first side, the received signals are elements of the alphabet, from which according to the specified rule, restoring the message for the information consumer on the first side, wherein the received signals after the predistortion, by the inversion operation, are used as the updated alphabet to generate, according to the rule specified by the parties, messages from the first side information source, transmitting the message, and in the receiving part of the second side, the received signals are alphabet elements, from which according to the rule stipulated by the parties, the message is restored and transmitted to the information consumer on the second side, wherein in the receiving part of the second side, by predistortion of signals, an updated alphabet is formed, to form, according to a rule specified by the parties, messages from the second party information source of the first one, thus, updating of the alphabet takes place constantly during information exchange between the parties.

EFFECT: high efficiency of transmitting multi-channel radio communication using broadband signals in a system.
