Abstract :
In satellite transmissions at frequencies above 10 GHz, deep signal fading, and hence severe outage, is mainly attributed to rain. Site diversity is an effective form of fade countermeasure. Statistics of seasonal and diurnal variations, together with average event length and separation, are needed to give the detailed insight for system design of DTH/VSAT systems. This paper presents a year´s worth of site diversity data measured from an equatorial mountainous coastal location and concentrates on the duration aspects
