The demand for high data rate, reliable wireless communications continues to grow rapidly. The number of connected devices is expected to explode in the near future as the use of of smartphones, the Internet of Things' devices such as health and fitness wearables will vastly increase (10s of billions for 5G). As the radio frequency (RF) spectrum is becoming very crowded, alternative and complementary technologies, such as visible light communications (VLC) have recently become very appealing. The advantages of using VLC are its inherent safety, the lack of interference, because VLC does not penetrate walls, and the huge free bandwidth. However, VLC has its drawbacks such as limited indoor coverage and limited mobility, and has to be used in a hybrid manner with RF links. Despite the recent interest in VLC and the availability of some commercial products such as LiFi, there remain many open problems to be addressed in order to fully exploit the huge available bandwidth with practical schemes. For example, the development of

对高数据速率、可靠无线通信的需求持续快速增长。随着智能手机、健康和健身可穿戴设备等物联网设备的使用量大幅增加（5G 将达到数百亿），预计连接设备的数量将在不久的将来出现爆炸式增长。随着射频 (RF) 频谱变得非常拥挤，可见光通信 (VLC) 等替代和补充技术最近变得非常有吸引力。使用VLC的优点是其固有的安全性、无干扰（因为VLC不穿墙）以及巨大的免费带宽。然而，VLC存在室内覆盖范围有限、移动性有限等缺点，必须与射频链路混合使用。尽管最近人们对 VLC 产生了浓厚的兴趣，并且一些商业产品（例如 LiFi）已经上市，但为了通过实际方案充分利用巨大的可用带宽，仍然有许多悬而未决的问题需要解决。例如，开发
