Abstract
A method of equalizer adaptation involves comparing equalizer output values with a center threshold, and with at least one of a pair of outer thresholds, and adapting the equalizer in order to increase the degree of eye opening.The values of the outer thresholds are adapted such that a fixed proportion of equalizer output values lie between the outer thresholds, and the equalizer coefficients are adapted such the separation of the outer thresholds is increased. The equalizer coefficients are adapted on the basis of equalizer output values which lie between the pair of outer thresholds.
