Abstract

The atmosphere is unstable and unpredictable environment, where are continual changes of the air refractive index. These changes cause fluctuation of optical power at the receiver site. The prediction of behavior of the atmosphere and effect of this behavior on the FSO link is very complicated or even impossible. Aim of this article is focused on statistical analysis of measured level signal RSSI of the FSO link and atmospheric properties measured by hydro-meteorological station. For measured data the statistical analysis tools were used. Next part of article is focused on determination of the linear regression model to calculate level of RSSI depending on the atmospheric properties. Two empirical equations are result for day and night time. These equations describe behavior of signal RSSI in 30 days interval. Finally, comparison of the obtained mathematical model with real measured data of RSSI was introduced for one week before and one week after the analyzed time interval.
