摘要

本文通过剖析多径多用户环境下阵列输出信号二阶统计量的数据结构，提出了一种基于特征分解的闭式阵列响应盲估计方法该方法适用于任何几何形状的阵列和未校难的阵列，且对信号特性和传播参数（散射源分布和入射角散布范围）的约束极少理论分析与仿真结果表明，该方法能够有效地进行阵列响应估计和信号分离，在空分多址（SDMA）的实现方面具有较强的实用性．

Abstract

A cled-form array response estimation （CARE） technique for blind source separation in wireles communication is developed by exploiting the data structure of second-order statistics of the array output in the presence of multipath.The proposed method achieves array response estimation with little constraint on signal property and propagtion environmentsuch as scatters or angular spread. Moreover

the array considered here can be of arbitrary geometry and even uncalibrated.
