摘要：
Due to suppression the influence of impulsive noise spikes (outliers) from desired signal direction of arrival in GPS signals, the Householder multistage wiener filter is improved, and the sample selected Householder multistage wiener filter is proposed. The enhanced algorithm is adopted in space-time anti-jamming processing in GPS receiver. The method has the ability of avoiding the influence of impulsive noise spikes (outliers) to weights calculation, and to the desired signal waveform. Simulation results indicate the algorithm achieves favorable anti-jamming performance.
