ABSTRACT:
A digital switch included within a satellite, processes uplink beams and the included traffic channels at a symbol level instead at a bit level. In this system the switch performs as a repeater on the per user basis and as a switch at the beam level. Individual user signals (i.e., channels) are separated from the uplink beam and recombined into the appropriate downlink beam.
