摘要:
自由度是多天线技术的根本,目前在对MIMO垂直自由度的开发已经有很多研究成果。有源天线阵列系统AAS的出现更加推动了这项研究的开展和应用,主要因为有源天线阵列可以动态的调整天线单元的振幅和相位来对天线辐射的水平维度和垂直维度进行强有力的控制。得益于良好的研究环境和技术成果,3D-MIMO在小区中的应用已经相当广泛,所以如何衡量3D天线在仿真场景中的性能提升变得很有必要,这也是本文探讨的重点。本文先介绍3D-MIMO信道建模,之后从链路级仿真角度对性能差异进行研究.

Abstract:
Freedom is the key to multi-antenna technology and recently there has been an increasing interest in the exploitation of MIMO elevation freedom. The emergence of AAS(active antenna system) has driven the research because it can dynamically adjust the amplitude and phase of each antenna element to provide adaptive control over both the elevation and the azimuth dimension. Benefiting from the good research environment and technology developments, 3D-MIMO has been widely used in the cells, so it is necessary to evaluate how much performance gained from the 3D-MIMO technology.Firstly, we introduce the principle of 3D-MIMO channel model and the we research the difference based on the link stimulation.
