Abstract
Apparatus includes a slave equalizer chain, which includes a first decoder and a first adaptive filter including first coefficients, and is configured to filter a first signal using the first adaptive filter to produce a first filtered signal, to decode the first filtered signal using the first decoder to generate a first output, and to adapt the first coefficients based at least on the first output. A master equalizer chain includes a second decoder and a second adaptive filter including second coefficients, and is configured to filter a second signal using the second adaptive filter to produce a second filtered signal, to calculate a weighted combination of the second filtered signal and the first filtered signal produced in the slave equalizer chain, to decode the weighted combination using the second decoder to generate a second output, and to adapt the second coefficients based at least on the second output.
