A method for increasing the transfer rate in HF radio communication systems is proposed, which, in comparison with existing methods, allows it to be doubled without expanding the frequency band occupied by the communication channel. The block diagram of one of the variants of the HF radio communication system that implements the proposed method is presented. The analysis of the operation of the communication system in the absence of external interference and the influence of interference concentrated over the spectrum is carried out.
