| 摘 要： | 在GPS接收机空时抗干扰的研究过程中,计算量大是目前主要的瓶颈,因此研究降维简化处理算法成为空时处理最关键的问题之一。在已给空时二维自适应滤波模型的基础上,通过对降维处理思想的分析,提出了一种基于多级维纳滤波(MWF)模型的改进方法——简化多级维纳滤波方法,并与一般的降维方法进行了均方误差(MSE)性能分析,仿真试验验证了该方法的有效性。

| Abstract: | In the study on space-time interference suppression in GPS receiver, dimension-reduced methods become one of the most critical issues because of the great amount of computations. After the model of space-time adaptive filter is offered, a simplified multistage nested Wiener filter （MWF） method, which is improved on the basis of the multistage nested Wiener filter （MWF） model, has been proposed through analyzing the dimension-reduced processing idea, and it is compared with some general dimension-reduced methods for mean square error （MSE） performance. The simulation result validates its validity. Good result is achieved when this simplified MWF method is applied in GPS space-time interference suppression. |
