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。
Aiming at the characteristics of wireless ultraviolet light scattering communication, three inter-link interferences in wireless ultraviolet (UV) light communication are introduced, and a Monte Carlo wireless ultraviolet non-line-of-sight (NLOS) single-scattering communication simulation model is established. The formula verifies the correctness of the model. The model was used to simulate the inter-link interference in the case of non-coplanar wireless UV communication. The results show that the reasonable adjustment of the receiving elevation angle and the viewing angle can reduce the inter-link interference and improve the communication System performance.
