Abstract

When the satellite navigation signals' interference power exceeds the receiver interference tolerance, the interference must be suppressed to ensure that the receiver works normally. Through analyzing the principle of the overlap window-based frequency domain narrowband interference suppression algorithm, this paper proposes using the reverse windowing approach to reduce the satellite signal distortion, and gives the selection basis of the frequency-domain FFT points combined with engineering practice, to further reduce the impact on self-correlation property of signal and local PN code.
