Abstract:
A method of operating an equalizer includes combining a Least Mean Squares (LMS) algorithm and a Least Squares (LS) algorithm to determine a set of equalizer tap values to be used in processing a signal. A channel impulse response (CIR) is computed, and an equalizer taps interval is then determined based on the CIR. The LS algorithm is used to determine a set of equalizer major taps based on the interval, and the LMS algorithm is used to determine a set of equalizer minor taps based on the interval.
