摘要
提出了根据接收光信号来估计发射端位置的优化方法。首先设定合理的门限,则可以选取合适的发射端节点拓扑以定位接收端位置,然后对误差较大的节点合理校正,提高了定位的精确度。讨论了该定位系统的性能,并分析了入射角抖动对VLC系统接收信号信噪比的影响。
An optimize method is proposed in the paper to improve the performance of position system based on visible light communication （VLC）. The optimum topology is chosen by setting a proper limit to distin- guish the power of receive signal,and then combined with a proper correcting method, the accuracy of position system is greatly improved. Finally, the performance analysis of the position system is carried out, and the ef- fect of irradiance angle turbulence on the performance of VLC is also discussed.
