HIGH-SPEED MULTICHANNEL SW-RANGE DATA TRANSMISSION SYSTEM Russian patent published in 2022 - IPC H04B7/02 

FIELD: radio communication.

SUBSTANCE: invention relates to radio communication equipment and can be used in shortwave (SW) range communication systems. To realise the stated technical result, the data transmission system is intended to operate in the 1.5 to 30.0 MHz frequency band to transmit information: by four autonomous channels with a nominal power of 500 W to 4 antennas; by four autonomous channels to two or one common antenna; at one frequency with the addition of powers of two or four channels in a single antenna with a total nominal output power of 1 kW and 2 kW, respectively; in order to receive information via eight reception channels and generate data of the panoramic view of the working frequency range; in order to exchange digital data (files) at speeds of up to 9.6 kbit/s in each channel (from one to eight channels in the upper and lower side bands).

EFFECT: increase in the speed of data exchange, automatic adaptation to the changing radio communication conditions, and ensured operation in the multi-channel mode.
