摘要/Abstract

摘要：

可见光通信技术主要基于发光二极管（light emitting diode，LED），依托现有照明网络基础设施完成信息传输与组网。针对室内多灯照明场景，研究了照明约束下的星座图优化与功率资源优化；并结合光学智能反射表面，动态调控反射信道，以提升系统传输数据率与覆盖范围。同时，通过初步研究，揭示了低频调制光信号的频闪效应对人体的影响，意味着LED光生物效应需要在未来的信号设计中全面考虑。

关键词: 可见光通信, 发光二极管, 光学智能反射表面, 频闪效应

Abstract:

Visible light communication (VLC), primarily based on light emitting diode (LED), supports the information transmission and networking through the existing infrastructure of the illumination network.The constellation optimization and the power resource optimization were investigated under lighting constraints with multiple LEDs for indoor environment.Moreover, the optical intelligent reflection surface was also researched to regulate reflection channels dynamically, improving both the transmission data rate and the coverage of the VLC system.In the meantime, the preliminary study revealed the flicker effect of low-frequency modulated optical signals on the human body, and the results suggest that the LED photo-biological effect should be considered comprehensively in the future signal design.

Key words: visible light communication, light emitting diode, optical intelligent reflecting surface, flicker effect
