基于高度的紫外光NLOS单次散射链路模型的研究

摘要

为了更精确、更全面地研究紫外光的通信性能,使之更适合于实际空间中的3维应用,在2维紫外光单次散射链路模型的基础上融入高度信息,并利用仿真计算了在添加高度信息与否的两种情况下接收功率误差的大小.结果表明,高度对于发射仰角和接收仰角潜在的影响直接引起接收功率的改变,甚至在某些情况下不能进行通信.高度信息的考虑对通信设备在实际空间中的应用给予了正确的指导.%In order to study the ultraviolet communication characteristics accurately and comprehensively so that it can be adopted in actual 3-D space application, with the height information synthesized in the single scattering link model, the error was computed with the height information or not.The result shows that potential interference of height on the transmitting angle and receiving angle will lead to receiving power changes, even lead to communication failure under some circumstances.Thus, it provides a good guideline to real application of the ultraviolet communication settings.
