摘要 大规模MIMO是5G移动通信系统的关键技术之一。通过实验教学使学生理解大规模MIMO无线信道特性是无线通信课程教学中的一个重要环节。针对传统大规模MIMO无线信道测量平台造价昂贵难以在实验教学中普及的问题,设计开发了一种价格低廉的虚拟大规模MIMO信道测量平台,使用矢量网络分析仪作为信号的发生器和接收器,运用LabVIEW开发基于3D打印机改造的移动测量平台的控制程序与交互界面,实现对大规模MIMO无线信道的自动化测量。该测量平台既能用于实验教学,也能用于学术研究,具有较好的应用价值。 Massive multiple input multiple output(MIMO)is one of the key technologies in the fifth generation mobile communication systems.Experimental teaching is an important part to make students understand the wireless channel characteristics of massive MIMO in wireless communication course.For the problem that the traditional wireless channel measurement platform of massive MIMO is expensive and difficult to become popular in the experimental teaching,this paper designs a virtual massive MIMO channel measurement platform,which is relatively cheap.Specifically,in order to achieve automatic measurement of massive MIMO channel,vector network analyzer is used as the signal transmitter and receiver,and LabVIEW is used to develop the control program and interactive interface of the mobile measurement platform,which is designed by using a 3D printer.The measurement platform can be used in both experimental teaching and academic research,and has important application value.
