ABSTRACT:
Baseline wander is compensated for by processing a read channel waveform to produce an estimated data decision signal, updating an estimated baseline wander signal by filtering the estimated data signal to produce an estimate of an associated pulse tail, combining that estimate with a prior estimated baseline wander signal to produce an updated estimated baseline wander signal, and combining the updated estimated baseline wander signal with the incoming signal at a next sample time. The operations continue recursively for next signal samples.
