METHOD AND DEVICE FOR SUPPRESSION OF NARROW-BAND INTERFERENCE AT RECEPTION OF COMPOSITE PHASE-MANIPULATED SIGNALS

FIELD: radio engineering, applicable in portable receivers of composite phase-manipulated signals. ^ SUBSTANCE: the method and device for suppression of narrow-band interference at reception of composite phase-manipulated signals are based on attenuation of the respective sections of the signal spectrum, which is attained due to the fact that the initial pseudorandom sequence is summed up in the path of the correlator reference signal with its copy delayed by a certain period of time, the delay time is determined by the delay search unit with the reference signal in the form of the sum of the initial pseudorandom sequence and the pseudorandom sequence with a varying delay as the time equal to the relative delay of the pseudorandom sequence, t which the voltage at the output of the delay search unit is minimal. ^ EFFECT: simplified realization, since three is no need to use a computer unit. ^ 2 cl, 5 dwg
