摘要

与传统的多输入多输出(MIMO)相比,拥有数十甚至数百个天线的大规模MIMO系统能够在容量和频谱效率方面提供更好的性能,是5G的一项有前景的技术。因此,大规模MIMO已成为国内外研究的热点。本文对近年来大规模MIMO的信道测量和信道模型进行了综述。并给出了团队提出的相关256个200 MHz带宽3.5 GHz的天线单元,验证了测量方法的合理性,以及移动场景下集群的空间演化。大规模分布式天线;信道测量;信道模型;虚拟测量;集群

A Survey of Massive MIMO Channel Measurements and Models
Compared with conventional multiple⁃input multiple⁃output (MIMO), massive MIMO system with tens or even hundreds of anten⁃ nas is able to give better performance in capacity and spectral efficiency, which is a promising technology for 5G. Considering this, massive MIMO has become a hot research topic all over the world. In this paper, the channel measurements and models of massive MIMO in recent years are summarized. Besides, the related 256 antenna elements with 200 MHz bandwidth at 3.5 GHz proposed by our team, the verification of rationality of the measurement method, and the spatial evolution of clusters in mobile scenario are provided. massive MIMO; channel measurement; channel model; virtual measurement; cluster
