摘　　要：简化计算是GPS接收机联合空时抗干扰的关键问题。多级维纳滤波(MWF)方法是一种先进的简化计算降维方法,本文在深入分析该方法的基础上,给出一种改进方法。与原MWF方法相比分析,本文方法在不影响接收机抗干扰性能的前提下,计算量进一步大幅下降,具有较高的可行性和实用性。仿真试验验证了该方法的有效性。Reduce computation is essential to joint space-time anti-jammer processing for GPS receiver. A new approach is proposed through studying on multistage wiener filtering method deeply. The method reduces the computation complexity while the performance of GPS receiver is not affected. The performance in numerical simulation demonstrates that the proposed method is effect and has a good performance.
