Ultraviolet and mid-infrared (MIR) constitute two extreme ends of the optical wireless communication band. Recently, there has been a rise in increased interest for research in these two spectral bands. For successful deployment of these technologies, the performance of these two spectrum bands needs to be thoroughly analyzed. We consider turbulence and noise effects over these spectral bands. Specifically, this paper considers separate and combined effects of atmospheric turbulence and various noise sources to model the channel impairment. The results show that the system performances are extremely sensitive to the choice of channel model. It is found that the relatively unused MIR spectrum offers excellent characteristics for outdoor optical communications in the presence of atmospheric turbulence.

湍流和噪声对光无线通信中紫外线和中红外光谱的影响

紫外线和中红外（MIR）构成了光学无线通信频段的两个极端。最近，人们对这两个光谱带的研究兴趣增加。为了成功部署这些技术，需要彻底分析这两个频段的性能。我们考虑在这些频谱带上的湍流和噪声影响。具体而言，本文考虑了大气湍流和各种噪声源的单独和组合影响，以对通道损伤进行建模。结果表明，系统性能对信道模型的选择极为敏感。发现相对未使用的MIR光谱在存在大气湍流的情况下为户外光通信提供了优异的特性。
