Satellite broadcast communication method and system

The invention provides for the design of a single beam communication satellite system covering a single service area, either uplink, downlink or both, by which rain fade effects are totally compensated. The rain fades, characterized by fixed margins, are not exceeded for a certain percentages of time. The service area must be large enough so that the statistical rain fades (in decibels) vary significantly over the service area. The single beam antenna must be electrically large enough and must have a beam forming network capable of multiple component beams so that a gain profile can be established for the antenna which compensates for the fixed margins established over the service area. Since no subscriber has excess fixed margin this results in a minimum power system. Other significant effects such as differences in slant range and other systemic variations over the service area also can be compensated.
