METHOD FOR RECEIVING SIGNALS INVOLVING PSEUDORANDOM FREQUENCY TUNING Russian patent published in 2003 - IPC

Abstract RU 2219656 C2

FIELD: radio engineering; communication systems using pseudorandom frequency tuning. SUBSTANCE: proposed method provides for estimating narrow-band noise whose frequency is same as signal frequencies, this being followed by using mentioned estimate to compensate for narrow-band noise in input mixture; in the process input mixture is multiplied in one of channels by reference sync signal, amplitudes of radio pulses produced from narrow-band noise being much higher than useful-signal radio pulse amplitude; upon blanking pulses whose amplitude exceeds threshold value radio pulse train is multiplied by reference sync signal. EFFECT: enhanced noise immunity. 1 cl, 2 dwg
