中文摘要：

在传统的二维多输入多输出（two dimensional multiple input multiple output，2DMIMO）信道模型基础上，引入仰角因子研究三维多输入多输出（three dimensional MIMO，3DMIM0）信道模型。推导出基于均匀线形阵列（uniform linear array，ULA）、均匀圆形阵列（uniform circular array，UCA）和均匀矩形阵列（uniform rectangle array，URA）的3D MIMO Kronecker信道模型，并进一步讨论了信号离开角和到达角分别服从高斯分布、拉普拉斯分布和VMF（Von Mises Fisher）分布时的信道模型。仿真结果表明，当信号空间角度服从VMF分布时所建信道模型容量最大，在该角度分布下基于ULA信道模型的容量优于UCA和URA。

英文摘要：

A three dimensional multiple input multiple output （3D MIMO） channel model is studied by introducing the elevation angle to the conventional two dimensional multiple input multiple output （2D MIMO） channel model. The 3D Kronecker channel model is deduced with typical attena arrays of uniform linear array （ULA）, uniform circular array （UCA） and uniform rectangle array （URA） respectively. Furthermore, channel models under Gaussian distribution, Laplacian distribution and Von Mises Fisher （VMF） distribution are also discussed. Simulation results show that when the angle of signal is VMF distributed, the channel model achieves the maximum capacity. In this case, the ULA channel model possesses bigger capacity than those of UCA and URA.
