ABSTRACT:
An apparatus that uses a lengthened equalization target filter with a matched filter metric in a Viterbi detector is disclosed. The equalization target includes a base partial response component, i.e., (1−D2), a fractional coefficient polynomial component to whiten the noise, i.e., (1+p1D+p2D2), and a time-reversed replica of the noise-whitening component. Thus, the time-reversed replica of the noise-whitening component comes from what was formerly a matched filter component.
