Visible light communication (VLC) is emerging as a viable alternative wireless transmission technology that could potentially alleviate the spectrum scarcity problem. VLC uses ordinary light sources such as light emitting diodes (LEDs) as the communication medium, and superposes a high frequency on/off operation on top of light sources for data transmissions. Compared to radio communications, the advantages of VLC include several orders broader in bandwidth, very little regulatory restrictions, ubiquitous light sources, and higher level of security for transmissions. One of the main challenges in the design of VLC at the physical layer is the issue of interference caused by simultaneous transmissions of multiple sources due to diffusion of lights emitted from regular light sources. While interference management for the Gaussian model (valid for the strong background light noise regime) is relatively well understood, it is mostly unexplored for the Poisson model (valid for the low background light noise regime). This project will design novel interference management techniques for VLC in the Poisson regime, analyze the corresponding transmission rates/throughputs for VLC, and develop information theoretic methodologies to characterize the fundamental communication limits on these transmission rates. The proposed research is expected to make substantial contributions to both applications and theory. On the application side, this project is anticipated to substantially advance our understanding of interference management for VLC, and provide important guidelines for designing high throughput and resource efficient VLC networks. On the theoretical level, the project will develop new stochastic calculus and information theoretic tools to advance our understanding of Poisson channels. The PIs will also use this project as a great platform to attract and train students from diverse backgrounds.

可见光通信（VLC）正在成为可行的替代无线传输技术，可能会减轻频谱稀缺问题。 VLC使用普通的光源，例如发光二极管（LED）作为通信介质，并在光源的基础上超级频率开/关操作以进行数据传输。与无线电通信相比，VLC的优势包括带宽更广泛的订单，几乎没有监管限制，无处不在的光源以及更高的传输安全性水平。 VLC在物理层设计中的主要挑战之一是由于从常规光源中发出的灯的扩散而引起的多个来源引起的干扰问题。虽然对高斯模型的干扰管理（对强背景光噪声状态有效）相对充分理解，但对于Poisson模型，它主要没有探索（对于低背景光噪声状态有效）。该项目将为VLC设计新颖的干扰管理技术，分析VLC的相应传输速率/吞吐量，并开发信息理论方法，以表征有关这些传输速率的基本通信限制。拟议的研究有望为应用和理论做出重大贡献。在应用程序方面，预计该项目将大大提高我们对VLC干扰管理的理解，并为设计高通量和资源有效的VLC网络提供重要指南。在理论层面上，该项目将开发新的随机演算和信息理论工具，以提高我们对泊松通道的理解。 PI还将将该项目用作吸引和培训来自不同背景的学生的绝佳平台。
