Adaptive channel equalizer with train mode

Adaptive channel equalizer (50) (VSB) demodulation signal (18) for processing comprising terrestrial broadcast high definition television information is vestigial sideband, it works in adaptive blind, training and decision-directed modes. VSB signal characterized in that a data frame format constituted by a series of data fields, each data field contains a data segment prefaced by a field sync segment. During a VSB data field after a field sync segment is detected, recirculation (35) several times through the equalizer equalized by the acceleration data received training.
