摘要
点对点可见光通信系统能够支持低能耗、高速率、大容量的数据交互业务。实际应用过程中,光源的选择与布局是关键研究技术之一。为进一步提高系统的通信性能,研究LED构成不同排列方式的阵列光源布局,提出了一种环形-角补偿的阵列光源布局。结果表明,这种光源布局方式能够有效增强接收端的光照度、接收功率及信噪比,并且提升接收端的信号质量,从而有益于点对点高速可见光通信系统的实现与推广。
The point-to-point visible light communication system can support data interaction services with low energy consumption,high speed and large capacity.In the process of its practical application,the selection and layout of light sources is one of the key research technologies.In order to further improve the communication performance of the system,the layout of array light sources with different arrangements of LEDs is explored,and a ring-angle compensation array light source layout proposed.The experiment results indicate that this novel LED layout method can effectively enhance the illuminance,receiving power and signal-to-noise ratio of the receiver,and improve the signal quality of the receiver,which is beneficial to the implementation and promotion of the point-to-point high-speed visible light communication system.
