介绍了紫外光通信特点和信道模型,以LED为光源、光电倍增管为光接收器设计无线紫外光数字通信系统方案,研制了无线紫外光通信设备样机,在不同条件下进行实验.实验结果表明,在夜晚,晴天,近距离,校准条件下的通信效果优于白天,下雨,远距离,未校准的条件下的通信效果,验证了无线紫外光通信的可行性.%The characteristics of UV communication and the communication channel are introduced in this paper. We design a wireless UV digital communication system with the UV LEDs as the light source and the photomultiplier tube as the optical receiver. A prototype device of UV wireless communication is developed. The experiments have been implemented under different conditions. The result of experiments shows that the communicational effect in the conditions such as in the night, sunny, short distance or alignment is better than in the conditions like daytime, rainy, long distance or misalignment. So the wireless UV communication is feasible.
