AN ALGORITHM FOR ESTIMATING SPATIAL SIGNATURE OF SIGNALS WITH GAINS AND PHASES OF SENSORS UNKNOWN

  • 摘要: 该文用均匀线阵研究了未知接收机通道特性下信号空间特征(=2sin/)的估计问题。利用均匀线阵的冗余结构,本文给出了基于信号子空间的ESPRIT-Like算法,得到了一个信号空间特征和通道特性的近似解。ESPRIT-Like算法对信号空间特征估计具有较好的稳健性;与B.Friedlander,V.C.Soon等人(1994)提出的其它迭代算法相比,ESPRIT-Like,算法具有计算量小的优点。数值仿真结果证实了本文算法的有效性并评价了算法的性能。
