紫外光非视距多次散射信道模型研究

Study on non-line-of-sight multiple scattering model

利用蒙特卡罗方法对紫外光非视距传输过程进行了模拟,讨论了传输过程中固体角的确定,仿真分析了系统的角度设置对传输损耗的影响。结果表明,增大收发仰角可以降低系统的传输损耗,并且小角度集中发射与大视场角接收可以降低系统的传输损耗。

The process of UV non-line-of-sight propagation is simulated by Monte Carlo method,the solid angle of propagation is discussed,and the effects of angles on path losses are simulated and analyzed.The results show that the increasing receiver and transmitter apex angles can reduce the path losses,and small transmitter beam divergence and large receiver half-field of view can also reduce the path losses of the system.
