Abstract:
An equalizer and an equalization method. The method includes receiving a data signal over a channel. The method further includes equalizing the data signal, by a blind partial response equalizer circuit, to provide an equalized output of the data signal. An estimation of partial response equalizer taps employed to determine the equalized output, by the blind partial response equalizer circuit, is carried out independently of true channel input symbols and detected symbols corresponding to the data signal.
