Patent ID: 7068731

Claim:
A receiver for use in a communications system that employs digitally modulated signals operating in a communications band of frequencies that is divided into two or more non-overlapping channels comprising: an input for receiving a data stream representative of the communications band, with each channel within the communications band having been converted to baseband and sampled at a rate of at least twice the symbol rate of the corresponding channel; an equalizer configured to equalize the data for each of the two or more non-overlapping channels; a timing recovery circuit configured to recover timing information for each of the two or more non-overlapping channels; a phase recovery circuit configured to recover phase information for each of the two or more non-overlapping channels; and an indexer that controls the cycling of data through the equalizer, the timing recovery, and phase recovery circuits so that data related to each channel is processed by each of the equalizer, the timing recovery, and phase recovery circuits in sequence, thereby requiring only one phase recovery, one timing recovery and one equalization circuit for all the channels within the communications band.
