METHOD FOR PROTECTION AGAINST NARROW-BAND AND PULSE INTERFERENCE FOR A DIGITAL RECEIVER Russian patent published in 2019 - IPC H04B1/10 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering and can be used in radio communication systems for transmitting data over a radio channel under conditions of a complex of deliberate interference. In the method of protection from narrow-band and pulse interferences for a digital receiver at the first stage, signal is filtered to preclude pulse interference. Further, the signal filtered from the most significant pulsed interference is further filtered to suppress narrow-band interference. Besides, spectrum of signal filtered from pulsed noise is supplied to spectrum analyser, which controls filtration of signal from narrow-band interference. At the last step, one more filtration is provided to suppress remaining pulse interference.

EFFECT: providing noise-immune operating mode of radio receiving equipment.
