FIELD: radio engineering and communications.
SUBSTANCE: invention relates to HF radio communication system and is intended for data transfer between mobile and fixed subscribers.
EFFECT: high efficiency of a HF radio communication system in terms of timeliness of transmitting messages by reducing the number of repeated requests for invalid data over a reverse communication channel, reliability of transmitting messages and their reproducibility with given accuracy at reception points are increased due to introduction of pilot signal processing units, accounting for continuously variable delay time of radio signals in a communication channel, provision of mutual synchronization between transmitting and receiving sides of the system.
