Abstract
Described herein are ground based subsystems, and related methods, for use in transmitting an optical feeder uplink beam to a satellite that is configured to receive the optical feeder uplink beam and in dependence thereon produce and transmit a plurality of RF service downlink beams within a specified RF frequency range to service terminals. Certain embodiments are related to a resource allocator for inclusion in a ground based subsystem, and methods for use therewith. Beneficially, the resource allocator, and methods for use therewith, eliminate any need for a satellite to perform any bandwidth allocation for the plurality of service downlink beams produced and transmitted by the satellite, thereby eliminating any need for the satellite to include an on-board channelizer. Such a recourse allocator can include a plurality of channels each of which can include an encoder and modulator, a channel filter, and a frequency up-converter.
