Method and system to increase capacity of high throughput satellite communication

A system to provide high throughput communications via a Radio Frequency (RF) satellite, the system comprising:

• a receiver to receive a plurality of information bit streams intended for a plurality of downlinks;
• a modulator to modulate an uplink stream comprising the plurality of information bit streams with an uplink modulation scheme to generate an uplink signal;
• a transmitter to transmit the uplink signal to the satellite;
• and
• a de-multiplexor, at the satellite, to partition the uplink signal into a plurality of downlink signals, each one of the downlink signals intended for one of the plurality of downlinks;
• an encoder to encode an uplink stream with a Forward Error Correcting (FEC) scheme;
• and
• a decoder and demodulator, at the satellite, to decode and demodulate the uplink signal,
• wherein
• the uplink stream comprises the plurality of information bit streams, and
• the uplink modulation scheme uses a higher order constellation as compared to an order constellation used by a modulation scheme used for at least one of the plurality of downlinks, and based on the FEC scheme, a Signal-to-Noise (SNR) ratio of an uplink and the uplink modulation scheme, the uplink stream has a frame error rate that is less than or equal to a desired frame error rate.
