METHOD FOR IMPROVING THE NOISE IMMUNITY OF A DUAL-CHANNEL RECEIVER WITH AN ADDITIONAL CHANNEL BASED ON A PHASE DETECTOR Russian patent published in 2023 - IPC G01R29/26 H04B15/02 

FIELD: noise immunity.

SUBSTANCE: improving the noise immunity of signal receivers, especially weak pulse signals at a high noise level, and measuring the parameters of structural differences between the mixture of the useful signal and noise and narrowband noise.

EFFECT: reduced signal-to-noise ratio, improved noise immunity. The technical result is achieved by modeling the passage of a mixture of useful signal and narrow-band noise through the main channel of the receiving device with an amplitude detector, estimating the noise immunity of the receiver, modeling the passage of narrow-band noise and the useful signal through the phase detector, measuring the voltage at the output of the phase detector, determining the magnitude of the output voltage of the phase detector.
