1. A forward-link satellite transmodulation system comprising:
a gateway system, comprising:
a forward feeder link creator that:
receives a first data stream for a first forward link signal and a second data stream for a second forward link signal; and
modulates the first data stream and the second data stream into a higher-order modulation forward feeder link having a higher-order digital modulation scheme; and
a transmitter that transmits the higher-order modulation forward feeder link to a satellite, wherein:
the satellite transmits data from the higher-order modulation forward feeder link as a first user equipment (UE) forward link having a first lower-order digital modulation scheme and as a second UE forward link having a second lower-order digital modulation scheme; and
the higher-order digital modulation scheme comprises higher order modulation than the first lower-order digital modulation scheme and the second lower-order digital modulation scheme.
