A receiver compensates for DC or baseline wander using a multi-tap filter to predict the shift in each sample of a received signal. The multi-tap filter is adaptive through coefficients updated during operation of the receiver. For each prediction, filter coefficients of the multi-tap filter change according to the error in the preceding prediction so that the changed coefficients would have provided a better prediction of the baseline shift for the preceding sample. The changed filter coefficients generally provide better future predictions.
