Interference Mitigation Technique using DOA Information of Interferences for the GPS Receiver

摘要

This paper proposes an interference mitigation technique for satisfying the minimum interference to noise ratio in GPS receiver. The DOA(Direction Of Arrival) information of interferences is used for estimating the interferences. And estimated interferences are subtracted from the signal at the reference antenna. The proposed technique has shown better performance than the typical PM(Power Minimization) method under the assumption that the DOA information of interferences has been already known.
