摘　　要：近年来,基于发光二极管(LED)的室内可见光通信(IVLC)技术正逐步成为宽带光通信接入领域的研究热点。目前世界各国正在推动5G产业化工作,其中一个关键要求是必须实现更高的数据传输速率。为了进一步提高IVLC的传输速率和系统性能,需要引进更为先进的调制解调技术。文章介绍了IVLC技术的研究背景和系统模型,总结了IVLC中正交频分复用(OFDM)、离散多音(DMT)和无载波幅相(CAP)调制及多输入多输出(MIMO)等技术的研究进展,并对IVLC技术未来的发展趋势和所面临的挑战进行了分析。Recently,Light-Emitting Diode(LED)-based Indoor Visible Light Communication(IVLC)technology is gradually becoming a research hot topic in the broadband communication access field.Currently,countries around the world are promoting the industrialization of 5G.One of the key requirements is that higher data transmission rates must be achieved.In order to further improve the transmission rate and system performance of IVLC system,it is necessary to introduce more advanced modulation and demodulation technologies.This paper first introduces the research background and system model of IVLC technology,and then summarizes the research progress of technologies such as Orthogonal Frequency Division Multiplexing(OFDM)modulation,Discrete Multi-Tone(DMT)modulation,Carrierless Amplitude-Phase(CAP)modulation and Multiple Input Multiple Output(MIMO)in IVLC.Finally,the future development trend and challenges of IVLC technologies are analyzed.
