The CCIR, considering that the broadcasting-satellite service (BSS) is normally expected to provide service to a relatibely large that in minimizing the effects of feeder-link noise on the overail link noise budget the cost and complexity of that the satellite output e.i.r.p.is maintained at the nominal output level during feeder-link fades by that higher up-link power requirements would affect only a few feeder-link stations; that in terms of availability, rain fades on the down link would only have a local affect on the performance that a further degradation of the overall link due to thermal noise occurs due to the non-linearity of the a)geographical area encompassing a large population of receivers; b> the BSS receiver will be minimized;c) employing techniques such as automatic gain control(AGC);d)that higher up-link power requirements would affect only a few feeder-link stations; e) whereas rain fade on the feeder link would affect performance over the whole service area.
