传统基于照明的光源布局方式在室内难免会存在光照度不均匀，造成通信盲区效应，这将会大大影响通信系统的可靠性。为了解决此类问题，本文首先以 4m X4m X3m 房间为模型，在常用的室内光源布局模式下，采用光照度补偿技术，对其进行合理的布局优化，得出了一种由 5 个 LED 阵列组成的光源布局方式。在这种布局方式下，可同时降低系统功耗和提高光照度均匀性；其次，为了同时兼顾 VLC 系统可靠性，采用室内接收平面的光照度标准差与通信中接收平面的平均误码率构建系统优化模型函数 f(L，i)，当 f(L，i)达到最小值时可同时保证接收平面的照度要求和通信误码率要求。最后通过仿真验证，当 L=0.35 米，i=0.025 米时，f(L,i)取得最小值，此时接收平面的光照度最小值为 301.26lx，最大值为 389.90lx，均匀度为 93.24%，系统照度标准差为 20.1，功耗为 140.5W，误码率为71039.6?? 。表明该系统可同时兼顾室内接收平面光照度分布的均匀性和通信的可靠性，为室内可见光通信光源布局提供了一种优化方法。
The traditional lighting-based light distribution in the indoor inevitably there will be uneven illumination, resulting in blind communication effect, which will greatly affect the reliability of the communication system. In order to solve this kind of problem, this paper firstly takes the 4m X4m X3m room as a model, and uses the illumination compensation technology to optimize the layout of the room in the commonly used indoor light source layout mode. A five-LED array Light source layout. In this layout, the power consumption of the system can be reduced and the illuminance uniformity can be improved at the same time. Secondly, in order to take account of the reliability of the VLC system at the same time, the system optimization is established by using the standard deviation of the illuminance of the indoor receiving plane and the average bit error rate of the receiving plane in communication The model function f (L, i), when f (L, i) reaches the minimum value, can simultaneously guarantee the illumination requirement of the receiving plane and the communication error rate requirement. Finally, the simulation results show that the minimum value of f (L, i) is obtained when L = 0.35m and i = 0.025m, the minimum illuminance of the receiving plane is 301.26lx, the maximum is 389.90lx and the evenness is 93.24% , The system illumination standard deviation is 20.1, the power consumption is 140.5W, the error rate is 71039.6 ??. It shows that the system can take into account the uniformity of illumination distribution and the reliability of communication in the indoor reception plane, and provides an optimization method for the layout of indoor visible light communication light sources.
