Abstract
A satellite system that includes a gateway, a satellite, and a user terminal. The gateway determines a modulation scheme based on a function of uplink and downlink signal quality and a defined relationship between the downlink modulation to the uplink modulation. The satellite includes an input demodulator configured to apply an input modulation and coding (modcod) scheme; an output modulator configured to apply an output modcod scheme; and an output modcod scheme selector configured to select an output modcod scheme for the output modulator based on the input modcod scheme according a predetermined relationship between input modcod schemes and output modcod schemes. The user terminal providing the gateway a measure of downlink signal quality.
