Partial-Response and Decision-Feedback Equalization

A signal space representation of fixed delay tree search for use with d=0 codes

“…However, use of the V A with channels that have a high degree of intersymbol interference (lSI) is unattractive because the detector complexity is related exponentially to the number of lSI samples. Detectors which equalize the channel to a partial response target with limited lSI have been successfully employed in magnetic recording channels [2], [3], [4].…”
