METHOD FOR DATA TRANSMISSION OVER SPATIALLY DISTRIBUTE RADIO TRANSMITTERS Russian patent published in 2023 - IPC H04B7/413 H04L1/06 

FIELD: wireless communication systems.

SUBSTANCE: invention relates to methods for radio exchange in systems with several spatially separated receivers and transmitters. Method of data transmission over space-diversified radio transmitters consists in forming a pair of complex symbols transmitted in parallel, encoding each generated pair of symbols with an Alamouti space-time code, forming an output matrix, transmitting elements of the upper and lower rows of the output matrix from the generated symbol pair through separate antennas. Antennas transmitting elements of different rows of the output matrix from the generated pair of symbols are located relative to each other at a distance not less than the value of the fading spatial correlation interval. The elements of the output matrix from the generated symbol pair are transmitted via one frequency subcarrier. Elements of the output matrices of the generated pairs of parallel-transmitted modulated symbols are transmitted via orthogonal subcarriers.

EFFECT: increased data transmission rate for spatially separated radio transmitters operating in the decameter range.
