long traceback trellis decoder and decision feedback equalization using a decision from the short traceback trellis decoder group

摘要

The decision determining the first symbol decision feedback equalizer of the present invention to be characterized by a relatively long processing delays determining a first symbol from the output of the feedback equalizer and the second symbol is determined , and determining a second symbol from the output of the decision feedback equalizer to be characterized by a relatively short processing delay , the first and second symbols to determine basis by the operation by determining the tap weights for the decision feedback equalizer groups . The first symbol decision can be derived from the output of the long traceback trellis decoder . The second symbol decision can be derived from a short delay the output of the output or the long traceback trellis decoder of the short traceback trellis decoder .
