Atmospheric-Turbulence Models
摘要
In order to overcome the influence of atmospheric-turbulence effect on the performance of optical wireless communication system, it is necessary to establish a turbulence model which can accurately describe the fluctuations of atmospheric refractive index. This paper summarizes the research progress of atmospheric-turbulence models at home and abroad, analyzes the theoretical establishment of different atmospheric-turbulence models in depth, and compares their application ranges. At the same time, the channel model of atmospheric established in the actual atmospheric-turbulence measurement is introduced. Finally, the development trend of atmospheric-turbulence model is forecasted.
