VLC可以同时执行通信和照明功能，有望成为下一代无线通信的重要组成部分。与传统的RF无线通信相比，VLC提供了许多显著的特征，例如其在未授权的可见光谱上的操作，其对高通信速率的支持，以及其对电磁干扰的免疫力。本文重点介绍了VLC系统中的码分多址技术，并讨论了VLC-CDMA技术的不同应用场景。特别地，将识别两种类型的VLC-CDMA系统，即，基于单极性码和双极性码的VLC-CDMA系统的性能将进行详细的分析和比较。
VLC can perform the functions of communications and lighting simultaneously, which is expected to be an important part of next-generation wireless communications. Compared to traditional RF wireless communications, VLC offers many salient features, such as its operation on unlicensed visible light spectra, its support of high communication rates, and its immunity against electromagnetic interferences. In this article, we focus on code division multiple access techniques used in VLC systems and discuss different application scenarios for VLC-CDMA technologies. In particular, two types of VLC-CDMA systems will be identified, i.e., unipolar codes and bipolar codes based VLC-CDMA systems, whose performances will be analyzed and compared explicitly.
