摘要：
By the year of 2018, the popularizing rate of common light emitting diode (LED) will reach 80%. The visible light communication (VLC) technology based on LED is expected to provide new scheme for the implementation of high-speed VLC. Researchers at home and aboard have studied technologies of modulation, coding or equalization and multiplexing, materials and chips in order to broaden the modulation bandwidth, improve the transmission rate and increase the transmission distance. The international research hotspots are analyzed and discussed, including technologies of carrier amplitude-phase modulation, orthogonal frequency division multiplexing modulation with adaptive bit power loading, hardware or software pre-equalization and post-equalization, and the principle and the performance of novel optical material. The latest researches are summarized in order to offer a reference for the future research of VLC. © 2017, Chinese Lasers Press. All right reserved.
