Abstract:
1. In a satellite communication system, a method for communicating between a central source and a plurality of user terminals via feeder frequency bands and service frequency bands, said method comprising: causing the generating of uplink feeder beams and downlink feeder beams, said uplink feeder beams and downlink feeder beams being associated with a plurality of gateways via a translator satellite having a different number of receivers than transmitters, said uplink feeder beams and said downlink feeder beams being characterized by a selection of feeder signals of first frequencies and first polarization slots, and each said feeder signal corresponding with a different color in a first selection of colors in a color map, each color being characterized by a unique frequency band and unique signal polarization; and causing the generating of a plurality of uplink service beams and downlink service beams, said uplink service beams and downlink service beams being associated with a plurality of user subscriber terminals via the satellite, said service beams being characterized by a selection of second frequencies and second polarization slots, the number of said second frequencies and second polarizations being less than the number of said first frequencies and said first polarizations and each said feeder signal corresponding with a different color in a second selection of colors in said color map, said second color selection being less in number than said first color selection, such that the feeder frequency bands and the service frequency bands are asymmetric among available frequency channels for communicating with enhanced efficiency between a central source and a plurality of user terminals via feeder frequency bands and service frequency bands.
