METHOD FOR INCREASING THE NOISE IMMUNITY OF DATA TRANSMISSION OVER A SHORT-WAVE RADIO CHANNEL IN A DEPARTMENTAL COMMUNICATION SYSTEM Russian patent published in 2022 - IPC H04B7/04 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and can be used to transmit data over a short-wave radio channel in a departmental communication system. In the method for transmitting data over a short-wave radio channel in a departmental communication system, due to the parallel retransmission of the signal and the formation of a virtual active phased array in the direction of the recipient of the message, the maximum signal-to-noise ratio is created, which also improves the noise immunity of the radio line. Additionally, there is a decrease in the spatial and energy availability of the sender of messages for the enemy’s electronic warfare system, which makes it difficult to open and suppress the entire radio communication line. In addition, unmasking signs of the sender of messages, which in this method is located outside the zone of possible intelligence, are eliminated.

EFFECT: increase in noise immunity based on a decrease in the energy and spatial availability of radio-electronic means, as well as the elimination of unmasking signs of radio-electronic means by which the operational and tactical affiliation of control points is determined.
