GNSS Space-Time Interference Mitigation: Advantages and Challenges
نویسندگان
چکیده
The use of space-time processing methods in GNSS interference mitigation is of great interest due to their effectiveness in both narrowband and wideband interference suppression. Techniques to reduce the distortion and bias on the cross correlation function due to space-time filtering are also very important especially for high precision GNSS applications. In this paper, different types of space-time interference mitigation methods are studied in terms of computational complexity, effectiveness and distortions. Distortions on cross correlation functions due to space-time filtering and related errors in position solution are analyzed using a real GPS L1 data set.
