均匀圆阵中时空信道多径参数的估计方法

摘要

We derive a method based on channel parameter matrix for theestimation of these parameters from the estimation of the vector channel impulse response(VCIR),using knowledge of the transmitted pulse shape function.Compared with the multi-dimensional MUSIC-like or ESPRIT-like ones,The algorithm does not need any search.It is a closed form solution,so it has slight computation burden.%本文给出了在矢量信道冲激响应(VCIR)可以估计出来的前提下，一种基于信道参数矩阵法的二维方向角与相对时延的联合估计方法，该方法充分利用了已知的信号码形信息，给出了一种无需进行搜索的闭式解，与基于多维MUSIC或多维ESPRIT的方法相比，具有运算量小的优势。
