摘要
降秩的多级维纳滤波技术在卫星导航接收系统中常被用于干扰抑制，传统的秩选方法会带来计算量增加的问题。文章通过多级维纳滤波技术的向前分解过程中互相关矢量特性的分析，提出了一种更为简单的秩选方法，该方法直接在向前分解过程中通过一个简单的判决即可完成秩选。计算机仿真结果证明了该方法的有效性和实用性。
The reduced-rank MWF（R-MWF） is applied to suppress interference in the satellite naviga- tion receiver system. The traditional rank selection increases computational complexity. Based on the analysis of cross-correlation vector in the forward recursion,a more simple technique for rank selection is proposed. Because the rank is determined by a criterion in the forward reeursion, the additional calcula- tions are avoided. The computer simulation results demonstrate its superiority and practicability.
