Efficient Coding and Decoding Techniques for Hybrid Radio Frequency and Visible Light Communication Links

对高数据速率、可靠的无线通信的需求持续快速增长。预计在不久的将来，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，联网设备的数量将大幅增加(5G将达到数百亿美元)。随着射频(RF)频谱变得非常拥挤，诸如可见光通信(VLC)等替代和补充技术最近变得非常有吸引力。使用VLC的优势在于其固有的安全性、无干扰，因为VLC不会穿透墙壁，并且具有巨大的空闲带宽。然而，VLC也有其缺点，如室内覆盖有限和移动性有限，必须与RF链路混合使用。尽管最近人们对VLC很感兴趣，并推出了一些商业产品，如LiFi，但仍有许多悬而未决的问题需要解决，以便通过实际方案充分利用巨大的可用带宽。例如，发展

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
