Abstract:
A method for adapting a mixed signal Infinite Impulse Response (IIR) Decision Feedback Equalizer (DFE) using pivot taps and monitor taps is disclosed. The method includes, for a given IIR path for a received signal, updating gain of the given IIR path using a respective pivot tap error-data correlation with a first Least Mean Square (LMS) update equation; and updating a time constant of the given IIR path using a respective monitor tap error-data correlation with a second LMS update equation.
