FIELD: physics, radio.
SUBSTANCE: invention relates to the field of radio communication, namely to the field of radio communication systems with frequency hopping. The time-varied procedure operational frequencies are used, depending on the time scale value of the communication system. Synchronization is performed by transmission of markers of special structure at the initial frequency corresponding to the current value of the time scale of the transmitter. The receiver periodically performs a serial search of the synchronization marker at the frequencies corresponding to previous, current and subsequent time intervals of the time scale of the receiver. Meanwhile on each frequency the duration of receipt is such that the skip of the marker transferred at this frequency is excluded. The received marker has the structure allowing to detect it due to the preset sequences contained in it, in addition the marker contains the value permitting uniquely identify the position of the received marker in a general layout of synchronization sending. After reception of the marker on the basis of its structure the receiver executes sync of the program of modification of frequency.
EFFECT: improved accuracy of synchronisation.
