Abstract: The automatic transversal filter equalizer is modified for improved startup performance in the presence of high initial distortion by providing control signals for adaptive adjustment of tap multipliers from correlations of the polarity of unequalized received data samples, rather than the polarity of data samples in the equalizer output, with the polarity of an error component in the equalizer output.
