摘要： 针对K复合衰落信道理论分析性能表达式涉及特殊函数的问题，研究K复合衰落信道模型下三维多输入多输出系统和速率性能，通过分析推导出基于最大比合并和迫零接收检测系统的和速率下界闭式表达式，所得下界同时考虑多径衰落、阴影衰落、路径损耗、3D天线辐射损耗和用户分布；基于所得和速率下界，针对大规模多输入多输出渐进性能进行分析.通过计算机仿真，证明了所得和速率下界充分逼近蒙特卡洛仿真结果，从而证明了理论分析的正确性.

Abstract: For the expression of the theoretical performance analysis of K composite fading channels involving special functions, the closed-form lower bounds on the sum rate of three dimensional multiple input multiple output (3D MIMO) systems over K composite fading channels maximal-ratio combining (MRC) and zero-forcing (ZF) receivers were derived, which include multipath fading, shadow fading, path loss, radiation loss of 3D antenna and user distribution. In addition, the asymptotic performance analysis of massive MIMO systems in view of the lower bound was performed. Correctness of the analysis is provided by the computer simulation, which demonstrates that the lower bounds of the sum rate can approximate the Monte-Carlo simulating values sufficiently.

Key words: three dimensional multiple input multiple output, K composite fading channels, lower bound rate, sum rate
