Patent ID: 7382828

Claim:
A method of operating a decision feedback equalizer comprising: correcting an output of the decision feedback equalizer to produce a corrected output characterized by a delay d; making first symbol decisions based on the corrected output, wherein the first symbol decisions are made by a first long traceback decoder having a parallel path memory output; storing an amount of the output of the decision feedback equalizer commensurate with the delay d, wherein the stored output comprises the most recent output of the decision feedback equalizer; making second symbol decisions based on the stored output and the parallel path memory output from the first long traceback decoder, wherein the second symbol decisions are made by a second long traceback decoder having a parallel path memory output; applying the parallel path memory output of the second long traceback decoder to the decision feedback equalizer; and, determining tap weights for the decision feedback equalizer based on the symbol decisions made by the first long traceback decoder.
