Continuous-time forward equalization for the decision-feedback-equalizer-based read channel

J.E.C. Brown, Paul J. Hurst

Open publisher page 5 citations

Abstract

A novel adaptive continuous-time forward equalizer (CTFE) for use with a decision-feedback equalizer (DFE) in the magnetic-recording read channel is presented. The forward equalizer is composed of one adaptive zero and can be constructed by adding a weighted version of the read-signal derivative to the read signal itself. The new equalizer is a viable alternative to traditional finite-impulse-response (FIR) forward equalizers in both performance and complexity.
