Apparatuses and methods of suppressing a narrow-band interference with a compensator and adjustment loops

摘要

Method of suppression of narrow-band interferences attending at the receiver input added to the useful broadband signal and noise.;There is a disclosed compensator rejecting narrow-band interferences by means of adjustment loops. Two general methods of construction of such loops are considered. The first general method is based on filtration of the in-phase and quadrature components of the error vectordifference of the interference vector and compensating vector. The second method is based on filtration of the amplitude and full phase of the interference signal. Automatic tuning of the compensator to the mean frequency and effective interference band is ensured.
