Original Abstract

While the propagation of RF waves in the atmosphere has been studied extensively and many reliable and proven models are available from ITU-R, similar support for FSO link design has not been fully established yet. The occurrences of fog events can cut-off the communication completely for hours or even days [Muh07]. Fog also imposes multiple propagation paths, which causes temporal broadening (dispersion) of transmitted pulses resulting in intersymbol interference (ISI) for high bandwidth links. The channel behaves like a low-pass filter during fog events. The significant effect of dispersion has been studied for ground-to-air/satellite communication through clouds [Wu07], but only few papers deal with fog whose physical properties are different. Rather complex digital detection techniques have been proposed to mitigate ISI [Lee06], but no chips are available at the moment.
