【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。
[Abstract]:When the indoor visible light communication system meets the illumination standard, the control variable method is used to change the number and layout of the LED chip to optimize the design of the optical front end, to obtain a more uniform light intensity distribution and to improve the fluctuation degree of the received power. By analyzing the results of normalized impulse response at some point in the room, it is concluded that the performance of VLC system is mainly affected by direct light. The illumination and power of the receiving plane are simulated in the line-of-sight link to verify the optimal light source layout design.
