Patent ID: 7016406

Claim:
An adaptive equalizer, comprising: an adaptive coefficient generator configured to receive an input signal and a control signal for generating tap coefficients; a feedforward filter coupled to the output of the adaptive coefficient generator and configured to receive the input signal; a slicer coupled to the output of the feedforward filter; a first summer coupled between the input of the slicer and the output of the feedforward filter; a multiplier coupled to a first input of the first summer; a first alignment circuit coupled to the input of the slicer; a second summer coupled to the output of the first alignment circuit and the output of the slicer for generating an error signal from the difference of the output of the slicer and first alignment circuit; a second alignment circuit coupled to the output of the slicer and which receives the error signal, the output of the second alignment circuit coupled to a first input of the multiplier; and a low pass filter configured to receive the error signal and the output of the second alignment circuit, the output of the low pass filter coupled to a second input of the multiplier.
