Methods and apparatus for controlling the operation of a equalizer

The operation control apparatus and a control method of an equalizer is disclosed. According to the invention, the signal-to-noise ratio of the equalizer output (SNR: Signal to Noise Ratio) measurement, and to do this by feeding back to the control unit to monitor the effective tap information of the group equalizer convergence information to monitor and at the same time equalizer in this equalizer in accordance select a tab to proceed the equalization operation of the group, and controls the operation of the equalizer. Thus, by not require a channel estimate for the proper operation of the equalizer is the equalizer structure can solve the problem of complicated for such selection of the tap coefficients according to the channel estimation. Eliminating the need for channel estimation may be implemented in a simple equalizer, select the appropriate tab to change the channel conditions and updates the count. Furthermore, by feeding back to monitor the output of the equalizer it is improved equalization performance of the equalizer. The equalizer tap coefficients updated, VSB
