Fade Dynamic Characteristics on Olympus 12.5 GHz Link

First data from the propagation experiments with the Olympus satellite have been analyzed at 12.5 GHz in Rome for a 18 months period, on an event basis. The dynamic characteristics of the attenuation due to rain are examined to extract the design figures for those communication systems making use of allocation of countermeasures on a dynamic basis. A suitable preprocessing of attenuation data has been performed. The correlation of both the slope and the duration of fade events with the attenuation level have been analyzed, giving useful results for fade-countermeasure applications.
