摘要
紫外光通信是一种新兴的基于大气散射和吸收的无线光通信技术,系统结构参数的选择对系统性能有重要影响。该文通过利用Luettgen提出的非视距单散射模型,比较了在不同仰角、光束孔径角情况下,损耗、延时、脉冲半宽展宽的变化特征,并给出了不同传输距离下能量密度的分布情况。根据仿真计算得到了不同紫外光通信条件下的损耗、时延和脉冲展宽。
Ultraviolet (UV) communication bases on atmosphere scatter and absorption. The structure parameters of system are important to UV system. The relationship between transmitter, receiver apex angle, beam divergence, and the value of loss-time delay are simulated by model developed by Luegtten. Energy distributing is elicited in the fixed angles. The value of loss and time-delay is given by simulation calculating in different conditions.
