  Time-domain adaptive filtering as a narrow-band interference suppression technique has great potential and broad prospects in navigation receiver anti-interference applications.In this paper,an adaptive notch filter design method based on Krylov subspace is put forward which achieves adaptive narrow-band interference suppression and optimal output SNR for navigation receivers.The method solves the issue of large computation amount in traditional Wiener filtering algorithm due to matrix inversion.Simulation results show that the algorithm has a simple structure and lower computation than that of the optimal filter.Thus,it is a practical algorithm for narrow-band interference suppression.
