Abstract

In the Visible Light Communication (VLC) system, the light emitting diode (LED) has a double function of illumination and communication. Aiming at the different distributions of luminous power and information access, a light source layout based on genetic algorithm is proposed. A $5\mathrm{m}\times 5\mathrm{m}\times 3\mathrm{m}$ indoor VLC system model is established, and four LEDs are used as light sources to analyze the relationship between different light source layouts and the received light power distribution. Genetic algorithm is used to optimize the distance between LED light sources in a square room to seek the best light source layout scheme. The results show that the value of peak power deviation (PDP) is 1.34 compared with the traditional layout scheme, which can minimize the variation of light power on the receiving plane and improve signal transmission performance if this system is also used to achieved broad information access.

基于遗传算法的室内VLC系统光源布局方案

在可见光通信(VLC)系统中，发光二极管(LED)具有照明和通信双重功能。针对不同的光功率分布和信息访问情况，提出了一种基于遗传算法的光源布局方法。建立了$5\ mathm {m}\乘以5\ mathm {m}\乘以3\ mathm {m}$室内VLC系统模型，以4个led作为光源，分析了不同光源布局与接收光功率分布之间的关系。采用遗传算法对方形房间内LED光源之间的距离进行优化，寻求最佳光源布局方案。结果表明，与传统布局方案相比，该方案的峰值功率偏差(PDP)值为1.34，在实现广泛信息接入的同时，能最大限度地减少接收平面光功率的变化，提高信号传输性能。
