A new statistical model of scintillation in RoFSO link and performance evaluation of WLAN system

This paper presents a new statistical model of optical intensity fluctuation (scintillation), considering time correlation of atmospheric propagated optical signal in RoFSO (Radio on Free Space Optics) channel. Relationships among frequency characteristic of RoFSO channel, variance of optical intensity, and atmospheric temperature are examined. A p.d.f(probability density function) of scintillation is also discussed. On the basis of these results, throughput performance of WLAN system affected by scintillation is evaluated.
