Abstract:
1. A receiver comprising: a receiver section for providing a signal having a plurality of different frequency channels, each frequency channel conveying a different bit stream; and a multi-channel signal tuner operative on the signal for recovering the different bit streams from at least two of the plurality of different frequency channels and for simultaneously providing the recovered different bits streams, wherein the multi-channel signal tuner utilizes a discrete cosine transformation (DCT) wherein the multi-channel signal tuner comprises: a sampler for sampling the signal to provide a number of decimated sample streams; a transform element operative on the number of decimated sample streams to provide transform output signals wherein the transform element utilizes the DCT; and a number of demodulators operative on the transform output signals to provide the recovered different bit streams.
