论文摘要
当用户配备多个天线时，我们研究了大量多输入多输出（MIMO）的上行链路性能。为此，我们考虑了一个广义的通道模型，该模型解释了视线传播和空间相关的多径褪色。最重要的是，我们采用了Weichselberger相关模型，该模型已被证明减轻了流行的Kronecker模型的缺陷。本文的主要贡献是使用最大比率组合和最小平方误差通道估计的上行链路频谱效率进行严格的封闭式表达。我们的结果是对以空间相关的通道的大规模MIMO结果进行了非平凡的概括，从而使我们能够为将来的大型MIMO系统设计合适的设计。数值模拟证实了我们的分析，并就不同的传播条件如何影响系统性能提供了有用的见解。
We study the uplink performance of massive multiple-input multiple-output (MIMO) when users are equipped with multiple antennas. To this end, we consider a generalized channel model that accounts for line-of-sight propagation and spatially correlated multipath fading. Most importantly, we employ the Weichselberger correlation model, which has been shown to alleviate the deficiencies of the popular Kronecker model. The main contribution of this paper is a rigorous closed-form expression for the uplink spectral efficiency using maximum-ratio combining and minimum mean square error channel estimation. Our result is a non-trivial generalization of previous results on massive MIMO with spatially correlated channels, thereby enabling us to have suitable designs for future massive MIMO systems. Numerical simulations corroborate our analysis and provide useful insights on how different propagation conditions affect system performance.
