摘要

对线性向量值通道x/spl rrr // spl Phi//下标i/M/下标i/x+z在矩阵和向量的维数变大时的渐近域进行了分析。用信道的Stieltjes变换给出了信道协方差矩阵的特征值分布。随着产品中出现的因素越来越多，渠道变得越来越病态。本研究对具有接收/发射天线阵列的蜂窝无线电信道具有重要意义。

On the asymptotic eigenvalue distribution of concatenated vector-valued fading channels

The linear vector-valued channel x/spl rarr/ /spl Phi//sub i/M/sub i/x+z is analyzed in the asymptotic regime as the dimensions of the matrices and vectors involved become large. The eigenvalue distribution of the channel's covariance matrix is given in terms of its Stieltjes transform. The channel gets more and more ill-conditioned the more factors appear in the product. The study is of interest for cellular radio channels with receiving/transmitting antenna arrays.
