摘要
大维随机矩阵理论(RMT)为理解多输入多输出(MIMO)信道和辅助MIMO无线通信系统设计提供了一种有效的分析工具。然而,以往基于大维RMT的研究依赖于发射相关矩阵为对角阵或传播信道矩阵为高斯的假设。当前,对于发射相关矩阵一般为非负定且信道元素为非高斯的信道,研究兴趣日益增长。这类信道模型出现在MIMO多址系统的若干应用中,例如小蜂窝网络(SCNs)。为解决这些问题,我们利用广义林德伯格原理证明,在高斯或非高斯独立元素情况下,这类随机矩阵的斯蒂尔杰斯变换在大维情形下是一致的。这一结果允许我们从已知的针对高斯MIMO信道发展的结果推导出非高斯MIMO信道的确定性等价(例如,斯蒂尔杰斯变换和遍历互信息),对于刻画SCNs的频谱效率具有重要意义。
