A method and an apparatus to control an equalizer. A signal to noise ratio o f an output of the equalizer is measured, the measured signal to noise ratio is f ed back to the equalizer controlling apparatus, and convergence information of the equalize r is monitored and at the same time effective tap information of the equalizer is monitored . Accordingly, one or more taps can be selected to perform equalization in the equalizer an d to control operation of the equalizer. Thus, it is not necessary to estimate channel information in order to properly operate the equalizer. Thus, since the channel information need not be estimated, a configuration of the equalizer is relatively simple. Additionally, it is possible to select a proper tap depending on a change in a channel environment and to update a corresponding tap coefficient. Accordingly, performance can be improved.</SD OAB>
