摘要：
We introduced a wireless optical communication system in this paper. Through the analysis of two main channels in the system: diffuse channel and light of sight (LOS) channel, we researched the influence of the multipath effect on the optical power distribution of the system and the influence of the SNR of the system under a given transmission rate. The method of reasonable layout of the LED array is proposed. The simulation results show that the diffuse channel transmission light power had a great influence on system can't be ignored. After optimization, the indoor light power distribution uniformity is improved, the area covered by bigger, better optical information transmission, system receiver SNR to meet the requirements of the indoor communication. This paper presents an approach to the study of optical power distribution aimed at indoor optical communication channel characteristics, and increase the efficiency of the indoor optical communication optimization scheme is given.
