摘要：A decision feedback equalizer (DFE) for equalizing PAM-N signals comprises acoefficient setting unit for setting a first group of most significant feedback coefficientsof the DFE to a predefined value selected from a group of predefined values; a

coefficients computation unit coupled to the coefficient setting unit for computing valuesof feedback coefficients of a second group of feedback coefficients other than the firstgroup of most significant feedback coefficients; a feedback (FB) unit for mitigating, usinga complete group of feedback coefficients, effects of interference from data symbolsthat are adjacent in time to an input data symbol, wherein most significant feedbackcoefficients of the first group are set to an optimal value computed during an

initialization of the DFE and feedback coefficients of the second group are computed bythe coefficients computation unit.
