Abstract
A method and apparatus that adjusts FIR taps based upon Viterbi margin counts. The FIR taps are adjusted by a) selecting one of N tap pairs for adjustment, b) adjusting the tap pair up one count and down one count, c) determining whether adjusting the tap pair up or adjusting the tap pair down provides a lower Viterbi margin count from the Viterbi detector and d) selecting the tap adjustment for the pair that provides the lower Viterbi margin count.
