摘要
建立了紫外光非视距通信模型,基于眼图原理,对紫外光非视距通信的通信距离和系统稳定性进行了深入研究,分析了散粒噪声和热噪声对通信性能的影响,并利用Opt i syst em进行实验。结果显示,一般环境下紫外光非视距通信距离可达到0.3km,热噪声对通信性能的影响比较大,并且得出一定环境下紫外光通信系统可接受的热噪声最大值为1×10-20W/Hz。
Built NLOS communication model. Based on the principle eye ,studied the communication distance of NLOS UV communication and system stability, analyzed the effect of shot noise and thermal noise on the performance of communication system, and done simulation through optisystem software, the results showed that UV NLOS communication distance can be up to 0.3km in general, thermal noise has great effect on the performance, and concluded that UV communication system can accept the thermal noise of a maximum is 1×10^-20W/Hz.
