Claim 2:
3. The satellite demodulator of claim 1, wherein the satellite channel is one of a plurality of satellite channels, each satellite channel having a respective one or more channel filters producing respective satellite channel filter distortions associated with the satellite channel, and the pre-equalizer subsystem further comprises:
a coefficient data store having a plurality of sets of compensation filter coefficients stored thereon, each set of compensation filter coefficients previously computed to at least partially compensate for the respective satellite channel filter distortions of a respective one of the plurality of satellite channels and stored in association with a respective channel identifier of the respective one of the plurality of satellite channels,
wherein the pre-equalizer filter block is presently configured to filter the channel-distorted sample stream based on a present set of compensation filter coefficients, the present set of compensation filter coefficients previously determined as stored in association with the respective channel identifier of the respective one of the plurality of satellite channels over which the ADC block is presently receiving the forward downlink communications.
