Abstract
A fast convergent pipeline adaptive decision feedback equalizer using a post-cursor processing filter is disclosed, which includes a feed-forward equalizer, a post-cursor processing filter, an adder, a slicer, a register, a pipelined feedback equalizer, a subtractor and a updating device. The pipelined feedback equalizer has a delay device coupled to the register for delaying its output signal, and a feedback equalizer coupled to the delay device for eliminating the post-cursor of the output signal. By using the post-cursor processing filter (PCF), it increases the operating clock rate with arbitrary speedup factor, and improves the convergence rate of the overall system.
