摘要
VLC(可见光通信)是一种新兴的无线光通信技术,它兼具照明和通信,具有多项优势和广阔的应用前景,已成为近年来研究的热点,结合MIMO(多输入多输出)等技术,可以大大提高其通信速率。研究人员已经提出了多种可用于VLC的MIMO模型和技术,国际上基于MIMO的光通信系统的研究有多点漫射MIMO系统、像素化MIMO系统、非成像MIMO系统和成像MIMO系统。文章对这些系统进行了探讨,总结了各种光MIMO通信模型的优缺点,可作为深入理解和进一步研究可见光MIMO通信技术的基础。
Having the functions of both lighting and communications, Visible Light Communication （VLC） is an emerging wireless optical communication technology. Having many advantages and broad prospects of applications, it has become a re- search hotspot in recent years. Combining with Multiple-Input Multiple-Output （MIMO） and other technologies, it can greatly increase the communication rate. Researchers have proposed multiple MIMO models and techniques applicable to VLC and there are multispot-diffuse MIMO, pixe[ated MIMO, non-imaging and imaging MIMO systems in the global researches on MI- MO-based optical communications systems. This paper investigates these systems and summarizes the advantages and disad- vantages of various optical MIMO communication models, laying the foundation for deep understanding and further research on MIMO-based VLC.
