A New Method for Cancelling CW Jamming in GPS Receivers

Abstract

Jamming cancellation is an important issue for global positioning system (GPS) receivers. As continuous wave (CW) jamming is the most widely used type of the jamming, this paper proposes a new anti-jamming system for mitigation CW jamming in GPS receivers. The proposed method employs infinite impulse response notch filters and wavelet transform for jamming mitigation. The proposed system can be implemented in the digital signal processor of the receiver. The computational complexity of the proposed method is low and it leads to an accurate positioning. Simulation results show that the proposed method has an average progress of 82.5% in term of positioning accuracy compared with standard method.
