摘要
针对无线紫外光散射通信的特点,介绍了无线紫外光通信中三种方式的链路间干扰,建立了基于蒙特卡罗的无线紫外光非视距(NLOS)单次散射通信仿真模型,并用理论公式验证了该模型的正确性。利用该模型仿真了无线紫外光通信非共面情况下的链路间干扰,结果表明:合理地调整工作链路接收端的接收仰角和视场角能更好地减小链路间干扰,提高通信系统的性能。
The characteristic of scattering and three kinds of inter-link interferences of wireless ultraviolet non-line-of-sight （NLOS） communication are studied. The wireless ultraviolet NLOS single scattering communication simulation model based on Monte Carlo method is established. The correctness of the model is verified by the theoretical formula. Using this model the non-coplanar inter-link interference in wireless ultraviolet communication is simulated. The results show that adjusting the receiving elevation and field angle of the working link receiver reasonably can reduce the inter-link interference and improve the performance of communication system.
