Abstract

See full text

A communication receiver includes a first signal processing circuit and a second signal processing circuit. The first signal processing circuit includes a first feedforward equalizer and a decision circuit. The first feedforward equalizer processes a received signal to generate a first equalized signal. The decision circuit performs hard decision upon the first equalized signal to generate a first symbol decision signal. The second signal processing circuit includes a second feedforward equalizer, a decision feedforward equalizer, and a first decision feedback equalizer. The second feedforward equalizer processes the first equalized signal to generate a second equalized signal. The decision feedforward equalizer processes the first symbol decision signal to generate a third equalized signal. The first decision feedback equalizer generates a second symbol decision signal according to the second equalized signal and the third equalized signal.
