METHOD OF RADIO COMMUNICATION WITH MIMO TECHNOLOGY AND PSEUDO-RANDOM TUNING OF OPERATING FREQUENCIES Russian patent published in 2023 - IPC H04B7/04 

FIELD: wireless communication systems.

SUBSTANCE: method of radio communication with MIMO technology and pseudo-random tuning of operating frequencies, characterized by the fact that, on the transmitting side, pairs of complex symbols transmitted in parallel are formed, the elements of the upper and the lower lines are transmitted through spatially separated antennas, the elements of the output matrices of the formed pairs of parallel transmitted modulated symbols are transmitted via subcarriers, subcarrier frequencies are formed in a pseudo-random manner, while information about the fading correlation frequency interval is supplied to the time-frequency matrix generator based on the results of ionospheric sounding with a periodicity not less than the duration of the stationarity interval of the decameter communication channel, radio exchange is carried out at the generated subcarrier frequencies for a time not exceeding the duration of the stationary interval of the decameter communication channel, after which the transition to the newly formed subcarrier frequencies is carried out.

EFFECT: enabled operation of a MIMO communication channel using pseudo-random tuning of operating frequencies to ensure immunity to interference.
