RADIO RECEIVER WITH DIGITAL SELF-CORRUPTED FREQUENCY CORRECTION Russian patent published in 2020 - IPC H04B15/04 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication engineering and can be used to create software-defined radio facilities with frequency-hopping spread spectrum (FHSS) in conditions of internal radiation effects caused by power sources of radio equipment, to ensure stable radio communication in a complicated interference environment. For this purpose, threshold device (6) is introduced, connected between second output of digital receiving channel (4) and input of digital conversion frequency (7) conversion unit, which reduces the number of frequency tuning transformations of secondary power supply (9) compared to the number of frequency tunings of the main receiving channel (MRC) in FHSS mode and thereby reduce the effect of transient processes on the sensitivity of the radio receiving device.

EFFECT: reducing the effect of transient processes on the sensitivity of the main receiving channel of MRC in FHSS mode in the absence of self-sustained frequencies of the radio receiving device generated by parasitic emissions of pulsed secondary power sources (SPS).
