GPS interference suppression using self-coherent feature of GPS signals

In this paper, a novel anti-jamming GPS receiver is proposed which relies on the unique structure of the coarse/acquisition (C/A) code of the GPS signals. The proposed receiver utilizes the inherent self-coherence property of the GPS signal to excise interferers which have different structures from that of the GPS signals. It is demonstrated that the GPS receiver is capable of providing high gains towards all desired GPS signals, while suppressing strong interferers.
