Zusammenfassung:A satellite receiver includes a signal cancellation tuner for processing a plurality of different transponder signals to simultaneously provide a plurality of different bit streams. The signal cancellation tuner includes (a) a demultiplexer for demultiplexing a received signal representing the plurality of transponder signals into a number of decimated signals, each transponder signal conveying a bit stream, and (b) a transform element operative on the number of decimated signals for providing at least two of the bitstreams simultaneously.
