室内可见光通信系统LED灯源功率优化及角度参数分析
LED Power Optimization and Angle Parameters Analysis for Indoor Visible Light Communication Systems
室内可见光通信系统的性能受到LED灯源发送功率，LED灯源半功率角（HPSA）以及接收器视角（FOV）的影响。本文提出了一种新颖的线性规划优化方法来优化LED灯源发射功率，此外分析了不同LED半功率角，不同接收器视角对系统通信，照明性能的影响。仿真结果表明采用本文优化算法，系统照明和通信质量有显著提升,同时系统消耗的功率显著下降，此外，仿真结果还表明LED灯源半功率角，接收器视角对可见光通信系统性能的影响是双面的，需要权衡。
he transmit power and half power semi-angle (HPSA) of LEDs as well as receiver's field of view (FOV) affect the performance of indoor visible light communication systems. In this paper, a novel linear programming (LP) method is proposed to optimize transmit power of LEDs. System performance with different HPSA and FOV is also investigated. Simulation results show that a significant improvement of illumination and communication quality as well as a remarkable reduction of power consumption is achieved after the proposed LP optimization. What's more, the influence of various HPSA and FOV on VLC system is found to be double-sided.
