摘    要:在阵列信号处理中,信号相关性的问题很容易引起混淆。一些文献简单地认为多径信号之间必定相干,从而在仿真实验中得出了不正确的结论。该文从信号相关性的基本概念出发,推导了单频点信号和带通信号下的互相关系数表达式,讨论了多径效应下信号之间的相关性,并指出了导致多径时延信号相关的各种参数,最后通过计算机仿真验证了文中的结论。

关 键 词:多径效应  相关性  宽带  阵列信号处理

Abstract:The issue of signal correlation is likely confused in array signal processing.In some published literatures,the multipath signals were simply considered as coherent signals,and then incorrect conclusion was obtained in simulation experiments.Starting from basic concept of signal correlation,expressions of cross correlation coefficient are derived from single frequency signal and band-pass signals.In addition,the correlation of multipath signals is discussed and the corresponding parameters associated with m...
Keywords:multipath effect  correlation  wideband  array signal processing
