Patent ID: 7283586

Claim:
An equalizer system for correcting distortions in a distorted signal, said system comprising: at least one equalizer processor, said at least one equalizer processor including a plurality of sequential weight taps for weighting the distorted signal with a weight value, said at least one equalizer processor further including a plurality of tap summers for summing the weighted signals together to provide a corrected signal; and an adaptive weight processor responsive to the corrected signal from the equalizer processor, said adaptive weight processor including a correlative error detection device that correlates a sequence of bits in the corrected signal with a predetermined sequence of correlation values to generate a plurality of correlation signals, wherein the predetermined sequence of correlation values represents ideal weight values for the equalizer processor, said correlative error detection device multiplying predetermined points in the corrected signal with a selected one of the correlation values to provide the plurality of correlation signals, said error detection device including an error summer that sums the correlation signals together to provide an error signal, wherein the magnitude of the error signal indicates whether the sequence of bits match the sequence of correlation values.
