摘　　要：针对室内可见光通信过程中的频闪效应,首先介绍了可见光通信中频闪效应的产生机制和对人体健康产生的影响。其次,为此提出使用MPPM调制方式来减弱频闪效应,并且使用两种方法来对此进行仿真实验,仿真实验结果进一步验证了想法的正确性,即MPPM调制可以缓解室内可见光通信的频闪问题。最后,基于仿真软件Multisim 14.0,设计了可见光通信系统的发射端电路和接收端电路。In view of the stroboscopic effect in the process of indoor visible light communication,the generation mechanism of stroboscopic effect in visible light communication and its impact on human health are introduced at first.Secondly,MPPM modulation is proposed to reduce the stroboscopic effect,and two methods are used to carry out simulation experiments.The simulation results further verify the correctness of the idea,that is,MPPM modulation can alleviate the stroboscopic problem of indoor visible light communication.Finally,based on the simulation software Multisim 14.0,the transmitter and receiver circuits of the visible light communication system are designed.
