【摘要】：LED兼具照明和數(shù)據(jù)通信功能,在室內(nèi)可見光通信(VLC)中,LED的布局對維持接收面上接收功率的穩(wěn)定分布有重要作用。室內(nèi)LED矩形布局下的接收功率分布并不能覆蓋整個接收面,存在接收功率中斷區(qū),無法實現(xiàn)最優(yōu)的VLC系統(tǒng)性能�？紤]室內(nèi)墻面及地板的一次反射,研究LED在不同位置的布局方案,采用粒子群優(yōu)化(PSO)算法分析LED布局方案,設(shè)計了能耗最小的LED圓形布局方案。仿真分析了LED矩形布局和圓形布局下的接收功率分布、信號中斷率、能量損耗以及信噪比分布,仿真結(jié)果表明LED圓形布局的VLC系統(tǒng)性能優(yōu)于矩形布局,需要的LED數(shù)量幾乎為矩形布局的一半,減小了VLC系統(tǒng)的碼間干擾。
[Abstract]:LED has both lighting and data communication functions. In indoor visible light communication (VLC), the layout of LED plays an important role in maintaining the stable distribution of receiving power on the receiving surface. The receiving power distribution in the indoor LED rectangular layout can not cover the entire receiving surface, and there is a broken area in the receiving power. The performance of the optimal VLC system can not be achieved. Consider the indoor performance of the VLC system. A reflection on the wall and the floor, the layout scheme of LED in different positions is studied. The particle swarm optimization (PSO) algorithm is used to analyze the LED layout scheme, and the LED circular layout scheme is designed for the minimum energy consumption. The simulation analysis is made of the receiving power distribution, the signal interruption rate, the energy loss and the signal-to-noise ratio distribution under the LED rectangular layout and the circular layout. The results show that the performance of the VLC system with LED circular layout is better than that of the rectangular layout, and the number of LED required is almost half of the rectangular layout, thus reducing the intersymbol interference of the VLC system.
