Interference suppression and multipath mitigation for global navigation satellite systems

摘要

This paper considers interference suppression and multipath mitigation in global navigation satellite systems (GNSS). A self-coherence based antijam GPS receiver has introduced, in which interference suppression is performed by exploiting the inherent self-coherence feature of the GPS C/A signal. In this paper, we equip the antijam self-coherent technique to mitigate multipath. Additionally, the Doppler effect performance is examined.
