METHOD FOR FULL DUPLEX MULTI-INPUT MULTI-OUTPUT (MIMO) PRECODING SYSTEM Russian patent published in 2023 - IPC H04B7/456 

FIELD: communications.

SUBSTANCE: in a method for a full-duplex multi-input multi-output (MIMO) precoding system, which is performed by a network component for full-duplex communication in multi-input multi-channel output (MIMO) systems, comprising the steps of generating with a precoding matrix generated in accordance with the channel conditions, a plurality of beams for a plurality of transmission signals, a plurality of beams for transmission signals are transmitted on a plurality of antennas, a plurality of received signals are received by a plurality of antennas, a plurality of corrected received signals are detected in a plurality of receivers, a plurality of signals are formed using a precoding matrix transmissions adjusted according to the channel conditions by a gradient procedure for estimating the matrix of input signals with a variable adaptation step, gradually decreasing with each iteration, and calculating the optimal coefficient that determines the rate of decrease in the adaptation step to reduce the matrix estimation error at later iteration steps.

EFFECT: reduced time for the formation of a corrected signal for transmission under conditions of a rapidly changing signal-interference environment in radio engineering systems for transmitting information.
