Abstract:
An equalizing apparatus for use in equalizing a received signal, comprising:an equalizer including a plurality of adjustable tap weights that equalizes the received signal based on values of the adjustable tap weights; a tap weight update calculation unit coupled to the equalizer and adapted to determine tap weight updates for use in adjusting the tap weights during operation of the equalizer; an offset memory that stores one or more tap weight update offset values; a summer coupled to the tap weight update calculation unit and to the offset memory, wherein the summer is adapted to combine each of the tap weight updates with one of the tap weight update offset values to produce a modified tap weight update and wherein the summer is coupled to the equalizer to provide the modified tap weight updates to the equalizer to adjust the tap weights; a demodulator coupled to the equalizer, wherein the demodulator produces a demodulated signal, and wherein the tap weight update calculation unit is coupled to the equalizer through the demodulator; and a decision unit coupled to the demodulator which decodes the demodulated signal.
