Abstract
A method and system of frequency domain equalization. In an embodiment, the frequency domain equalizer system includes a transmit driver. A receiver decision circuit is communicatively coupled to the transmit driver. The receiver decision circuit may have an input signal and an output signal. An all-pass filter may be communicatively coupled to the transmit driver and the receiver decision circuit. The all-pass filter having an all-pass input signal which comprises an integration of a summation of the receiver decision circuit input signal and the receiver decision circuit output signal, each signal being acted upon by at least one band-pass filter.
