Abstract :
A rapid and reliable acquisition procedure is proposed for DFE detection. This new approach eliminates the false-lock problem which arises in these detectors due to the decision feedback. The acquisition process comprises four distinct steps. It is illustrated with MDFE detection on the magnetic recording channel. Monte-Carlo simulations verify the robustness and accuracy of the acquisition process
