Abstract
A method and system for antenna pattern synthesis based on geographical distribution of subscribers allows more efficient use of satellite power resources in order to provide communications services to terrestrial-based subscribers (FIG. 1, 105, 115, 125, and 135). The method entails the grouping of terrestrial-based subscribers into communication beams (FIG. 5, 530) where gain is maximized (550) at the centroid of each beam. Additionally, gain in the directions of interfering emitters is minimized (540). A processor (FIG. 7, 740), which can be resident within a satellite (200), can perform the necessary processing to synthesize communication beams which service the terrestrial-based subscribers (105, 115, 125, and 135).
