采用多级最小模方法的空时抗干扰GPS接收机
Multistage minimal module method for space-time interference suppression GPS receivers
摘要
Abstract
For suppression of the influence of impulsive noise spikes (outliers) from desired signal direction of arrival in GPS signals, the multistage minimal module cascaded canceller is proposed. The method substitutes the weights of the multistage Winner filter for the minimal module weights, which have the minimal module of the samples quotient, and is adopted in space-time anti-jamming processing in the GPS receiver. The method has the prominent ability to restrict the influence of impulsive noise spikes ( outliers) from desired signal direction of arrival to adaptive weights, and the ability of low complexity, as well as fast convergence. Simulation results indicate the method achieves a better fast convergence ability and good performance in reducing the influence of impulsive noise spikes (outliers) on adaptive weights.关键词
