| Satellite-to-Earth links are subject to several propagation effects in the troposphere, being rain attenuation the impairment that can cause the deepest fades. In this paper, the duration of both fades and the intervals between consecutive fades (inter-fade intervals) are characterized on the basis of the results of a long-term slant-path Ka-band propagation experiment carried out in Madrid, Spain. The experimental and statistical results included in the paper correspond to seven complete years of measurements, a period large enough to characterize not only the average-year statistics of fade dynamics, but also their variability, which is assessed on the basis of annual statistics of durations. The obtained average-year statistics of fade durations are in many cases close to the predictions made by ITU-R (International Telecommunication Union - Radiocommunications) and CRC (Communications Research Centre Canada) models, although the predictions could be improved with a better selection of the parameters of the distributions used in the models. Inter-fade duration statistics are also presented and related to recent modeling efforts. The inter-annual variability of statistics, such as the relative number of fades, is quantified and found to be low, except for the higher attenuation thresholds or the highest durations considered in the study. | |
