摘要/Abstract

摘要： 针对二维多输入多输出（2D MIMO）系统只考虑天线水平辐射增益的影响而忽略垂直辐射增益，以及K复合衰落信道下和速率的确切闭式表达式涉及复杂函数，提出两种在K（Rayleigh/Gamma）复合衰落信道下3D分布式MIMO （3D-MIMO）系统基于迫零（ZF）检测的可达和速率上界。该上界同时考虑瑞利（Rayleigh）多径衰落、伽马（Gamma）阴影衰落、基于几何的路径损耗，3D天线辐射损耗以及用户分布。实验结果表明：所得闭式表达式与蒙特卡洛仿真结论充分相一致。

Abstract: Concerning the problems that Two-Dimensional Multiple-Input Multiple-Output (2D MIMO) systems only consider the effects of horizontal radiation pattern, ignoring the effects of vertical radiation pattern, and the closed-form on the sum rate of 2D MIMO system over K (Rayleigh/Gamma) fading channels involves special functions, two closed-form upper bounds on achievable sum rate of Three Dimensional Distributed Multiple-Input Multiple-Output (3D D-MIMO) systems with Zero-Forcing (ZF) receivers over K composite fading channels were proposed. The upper bounds considered Rayleigh multipath fading, Gamma shadow fading, geometric path-loss, 3D antenna radiation loss, and user distribution. The experimental results show that the obtained expressions accurately match with the Monte Carlo simulation conclusions.

Key words: Three-Dimensional Multiple-Input Multiple-Output (3D-MIMO), K composite fading channel, upper bound, sum rate, Zero-Forcing (ZF)
