Abstract:
A signal receiver inputs a signal, computes a set of equalizer tap values during a signal acquisition phase by applying an algorithm iteratively to a given set of training data contained within the signal, and uses the set of equalizer tap values to perform signal equalization during the signal acquisition phase. The algorithm includes computing and applying phase correction to the pre-equalized signal at each adaptation step to correct for phase error related to the main path only, of the input signal.
