Abstract
An adaptive channel equalizer ( ) for processing a demodulated VSB signal containing terrestrial broadcast high definition television information operates adaptively in blind, training, and decision-directed modes. The VSB signal is characterized by a data frame format (FIG. 2) constituted by a succession of data fields each containing a data segment prefaced by a field sync segment. Equalization is expedited by recycling ( ) received training data through the equalizer more than once during a VSB data field after a field sync segment is detected.
