Interference suppression method for space-time navigation receivers based on samples selection Householder multistage wiener filter

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 was improved, a samples selection Householder multistage wiener Alter was proposed. The enhanced algorithm employed by space-time anti-jamming processing in GPS receiver, with the ability of avoiding the impulsive noise spikes influence of weights calculation, and hold the desired signal unchanged. Simulation results indicate the algorithm achieved favorable anti-jamming performance.
