Abstract
An equalizer. The equalizer, either operated in a blind mode or a decision directed mode, comprises a feed-forward filter, a feedback filter, a decision device, a control circuit, and a multiplexer. The feed-forward filter receives an input signal. The feedback filter filters an equalized signal. The combiner combines the feed-forward filtered signal and the feedback filtered signal. The decision device maps the combined signal to one symbol of a symbol set. The control circuit receives the combined output and generates a slice control signal. The multiplexer selects the combined signal or the mapped signal as the equalized according to the slice control signal when operated in the blind mode.
