摘要
在室内可见光通信(VLC)系统满足照度标准的情况下,采用控制变量法来改变LED芯片的数目和布局来优化光学前端的设计,得到更均匀的光照度分布,改善接收功率的波动程度。通过对房间内某点的归一化冲激响应结果分析,得到VLC系统的性能主要受直射光的影响。在视距链路中对接收面的光照度和接收功率进行仿真,验证了最优化光源布局设计方案。
In the case of indoor visible light communication system satisfy the standard of illumination, the controlling variable method is used to change the number and layout of LEDs to optimize the design of the optical front end, in order to improve the uniformity of illumination and volatility of receiving power. The analysis of impulse response at some point shows that the performance of VLC system is mainly affected by direct light. The optimal layout scheme is validated by simulations of illumination and receiving power.
