Abstract
An adaptive decision feedback equalizer includes a filter module, a compensation module, and a slicer module. The filter module generates a filtered signal by adaptively filtering an input serial data signal to reduce inter-symbol interference in the serial data signal. The compensation module generates a compensated signal by equalizing amplitudes of frequency components of the filtered signal in a compensation frequency range to reduce inter-symbol interference in the filtered signal. The slicer module determines logic states of serial data in the compensated signal and generates an output serial data signal including serial data having the determined logic states.
