A self-coherence anti-jamming GPS receiver.
In this correspondence, we present a self-coherence antijamming global positioning system (GPS) receiver that relies on the unique structure of the coarse/acquisition (C/A) code of the GPS signals. Since the C/A-code is repeated 20 times within each navigation symbol, the GPS signal exhibits strong self-coherence between chip-rate samples separated by integer multiples of the spreading gain. The proposed receiver utilizes this inherent self-coherence property to excise interferers whose temporal structures are different from those of the GPS signals. It is shown that the proposed receiver is a blind receiver that does not require the knowledge of the satellite positions.
