ABSTRACT:
In one embodiment of the invention, a tap-leakage generator includes an error filter and an updater. The error filter filters a decision error provided by the adaptive filter using a leakage factor. The adaptive filter has N taps. The updater updates N equalizer coefficients to the N taps using the filtered decision error. The updater receives N equalizer data from the N taps.
