ABSTRACT:
An improved equalization apparatus includes a coefficient update module for receiving a filtered signal from the equalizer filter circuit and for generating a set of filter coefficients including a set of coarsely updated coefficients or a set of finely updated coefficients for equalizer filter. The coefficient updating module includes a first memory means for storing a set of coarse error values, and for generating, in response to a filtered data sample, a first error signal representative of the corresponding coarse error value; and a second memory for storing a set of fine error values, and for generating, in response to a filtered data sample and a control signal, a second error signal representative of the corresponding fine error value.
