Abstract
An equalization system used in a communication receiver has multiple equalization stages. A front equalizer supplies equalization output to a feed back filter in a rear equalizer to speed initialization of the rear equalizer. In addition, the rear equalizer supplies decision output to the front equalizer to estimate errors so as to provide more accurate tap coefficient adjustments. Both the front equalizer and the rear equalizer can be implemented with iterative equalizers to further enhance equalization performance.
