METHOD FOR ADAPTIVE DATA TRANSMISSION IN A RADIO LINK WITH PSEUDO-RANDOM TUNING OF OPERATING FREQUENCY Russian patent published in 2019 - IPC H04B1/713 

FIELD: radio engineering and communication.

SUBSTANCE: invention relates to radio communication and can be used in adaptive radio lines with pseudo-random tuning of operating frequency. Method consists in elimination of unusable frequencies during operation of a radio link and communication only at frequencies with required quality, which increases time of continuous serviceable operation of a radio link, and is characterized by that, at the transmitting end of the radio link, based on the correspondent frequency status list, determining transmission frequencies, generating a digital test sequence which, in combination with a frequency state list, is added in the form of a service slot to the information frame, emitting modulated slots into space, on the receiving side, selecting a service slot, dividing the test sequence and the correspondent frequency status list, determining the number of incorrectly received bits of the test sequence, deciding on frequency exclusion, generating a new frequency state list, if the specified number of unusable frequencies is exceeded, all frequencies in the status list are determined to be suitable.

EFFECT: high timeliness of transmitting messages in a noise-protected radio link with pseudo-random tuning of operating frequency.
