摘　　要：为了进一步研究非视线链路情况下的可见光通信系统,建立了非视线链路通信空间模型,在此基础上设计基于非视线链路的可见光通信系统收发端并完成通信。实验结果表明:在保证可见光通信过程中接收端只接收到非视线链路传输的信号时,通信系统仍然能正常完成通信,采用非视线通信可以解决因视线链路被遮挡而无法进行通信的问题。In order to study the visible light communication system in the case of non-line-of-sight link,this experiment establishes a non-line-of-sight link communication space model.On such basis,this paper designs the sender and receiver of the visible light communication system to complete the communication based on the non-line-of-sight link.The experimental results show that in the process of visible light communication,when the receiver only receives the signal transmitted by the non-line-of-sight link,the communication system can still complete the communication normally,non-line-of-sight communication can solve the problem that communication cannot be carried out because of the line-of-sight light is blocked.
