Patent ID: 7266145

Claim:
An apparatus including an adaptive signal equalizer, comprising: adaptive equalization circuitry that receives at least a plurality of adaptive coefficient signals and in response thereto receives and equalizes an input data signal to provide an equalized signal; signal slicer circuitry, coupled to said adaptive equalization circuitry, that receives and slices said equalized signal to provide a sliced signal and a difference signal corresponding to a difference between said equalized signal and said sliced signal; and adaptive coefficient signal generator circuitry, coupled to said signal slicer circuitry and said adaptive equalization circuitry, that receives said input data signal and said difference signal and processes one of said input data signal and said difference signal to provide first and second aligned signals which are substantially temporally aligned, and processes said first and second aligned signals together to provide said plurality of adaptive coefficient signals, wherein said adaptive coefficient signal generator circuitry comprises: signal delay interpolation circuitry that receives said plurality of adaptive coefficient signals and in response thereto receives and interpolates said one of said input data signal and said difference signal to provide an interpolated delayed signal; and first signal combining circuitry, coupled to said signal delay interpolation circuitry, that receives and combines said interpolated delayed signal and another of said input data signal and said difference signal to provide said plurality of adaptive coefficient signals.
