| 中文摘要: |
| 一个完整的通信系统必须包含完整的双向通信链路，也就是含有上行链路与下行链路，上行链路一直以来是双向通信系统的难题。而近年来可见光技术飞速发展，其具有无电磁辐射、通信容量大且绿色环保等优点可以作为传统上行链路方案的补充。本文首先介绍了可见光通信的应用场景和系统构成，并对今年来可见光上行链路国内外研究现状进行综述，另外给出了可见光上行链路的各种方案如可见光与射频、可见光与可见光、可见光与电力载波以及单光源逆向调制技术4种方案，最后总结了可见光通信上行链路目前面临的问题，并总结了各种方案的优缺点以及对未来发展趋势进行展望。 |
| 英文摘要: |
| A complete communication system must encompass a full two-way communication link, which includes both uplink and downlink. The uplink has always been a challenge for two-way communication systems. In recent years, the rapid development of visible light communication technology, with its advantages of no electromagnetic radiation, large communication capacity, and environmental friendliness, can serve as a supplement to traditional uplink solutions. The article first introduces the application scenarios and system composition of visible light communication, and then provides a review of the current research status of visible light uplink at home and abroad in recent years. In addition, it presents various schemes for visible light uplink, such as visible light with radio frequency, visible light with visible light, visible light with power line carrier, and single-source reverse modulation technology. Finally, it summarizes the current issues faced by the visible light communication uplink and summarizes the advantages and disadvantages of various schemes, as well as prospects for future development trends. |
