Claim 9:
10. The pre-equalizer system of claim 9, further comprising:
a coefficient data store having a plurality of sets of compensation filter coefficients stored thereon, 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;
each set of compensation filter coefficients is 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 configurable to filter the channel-distorted sample stream based on a present set of compensation filter coefficients by determining a present satellite channel of the plurality of satellite channels over which the ADC block is presently receiving the forward downlink communications, and by selecting the present set of compensation filter coefficients as the one of the plurality of sets of compensation filter coefficients stored in association with the respective channel identifier of the present satellite channel.
