摘要

我们给出了HFH*的无序特征值的边际密度分布的封闭表达式,其中F是输入协方差,H是表示MIMO(多输入多输出)瑞利衰落信道的矩阵,该信道在链路两端(发射机或接收机)具有单侧相关,其中天线数量没有限制。利用上述分布,我们推导出容量的解析表达式。通过几个具有实际意义的关联结构的例子对所发现的表达式进行了评估。

Capacity of MIMO channels with one-sided correlation
We present closed-form expressions for the marginal density distribution of the unordered eigenvalues of HFH* where F is an input covariance and H is a matrix representing a MIMO (multi-input multi-output) Rayleigh-faded channel with one-sided correlation at either end of the link, transmitter or receiver, with no constraints on the numbers of antennas therein. Using the foregoing distribution, we then derive analytical expressions for the capacity. The expressions found are evaluated through several examples conducted with correlation structures of practical interest.
