Narrowband Multipath Signal Reception Beamforming Algorithm Based on Anti-diagonal Unit Matrix

  • 摘要: 针对多径环境下传统Capon 波束形成器性能下降的问题,该文首先分析了期望信号对消的原因:对应期望信号和多径干扰的阵列输出间的相位差始终在 附近变化。然后利用反对角单位阵构造新的阵列接收数据协方差矩阵和导向矢量,并根据最小方差无畸变(MVDR)准则求取最优加权矢量进行阵列输出。该算法无需估计多径和非相关干扰信号的来向,且可以通过调整选取的阵元个数获得更优的阵列输出性能。仿真实验表明该文算法的性能优于传统Capon 和多径信号接收类算法。
