摘要/Abstract

摘要：

现有的多输入多输出（MIMO）信道仿真模型主要基于二维（2D）平面，不能反映实际的三维（3D）电波传播环境。在WINNER 2D模型的基础上研究建立3D MIMO信道仿真平台。加入空间垂直维后，天线方向图需要从2D扩展至3D，并对3D天线阵列构成的MIMO系统进行建模。利用实验数据对城市微小区场景进行仿真验证，可以看出三维MIMO信道参数仿真与实验结果符合较好。3D MIMO信道间的相关性要比2D大，但3D MIMO的信道容量相比2D会有比较大的提升。

Abstract:

The existing MIMO channel simulation models are based on two-dimensional（2D）plane and can’t match with a three-dimensional（3D）radio propagation environment.A 3D MIMO channel simulation platform based on WINNER channel model was set up.After adding the vertical dimension in the model，the array patterns should be extended from 2D to 3D and 3D MIMO channel simulations were implemented.The simulation results of 3D MIMO channel parameters were validated by comparisons with the 3D measurements for an urban micro cell，good agreements could be observed.Simulation results show that the 3D channel correlation is bigger than 2D，however， its capacity has bigger improvement compared with 2D.

Key words: 3D MIMO, channel simulation, channel parameter, spatial correlation, channel capacity
