Abstract

A poster to show the fractal analysis of rain fields for communications system design. Communications systems operating at frequencies above 10 GHz suffer from severe attenuation due to rain, clouds and atmospheric gases, though rain is the dominant factor responsible for most of the time-variant fading experienced. Systems currently in operation deal with this problem by allocating a fixed fade margin. However, for higher frequencies this is economically unfeasible as the fade margin required to provide a set quality of service becomes too high. For this reason, much attention is being paid to methods of dealing with fades on an adaptive and reactive basis. Such methods are collectively known as Fade Mitigation Techniques (FMTs). One FMT, which concerns the (time-variant) two dimensional distribution of the precipitation rate R(x,y,t) (mm/h), is called Space Diversity.
