基于数据选择Householder多级维纳滤波导航接收机空时抗干扰方法

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 arti-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 perforrance.%针对抑制GPS信号中期望信号方向的冲激毛刺干扰影响问题,对Householder多级维纳滤波方法进行改进,提出一种数据选择Householder多级维纳滤波器.改进方法用于GPS信号空时抗干扰处理中,可以避免期望信号方向的冲激毛刺干扰对最优权值计算的影响,同时保持期望信号不受影响.仿真结果验证了算法良好的抗干扰性能.
