Abstract
A system that includes a Viterbi Equalizer having adaptive signal levels is disclosed. Each branch metric of the Viterbi Equalizer compares the value of the incoming bit to one of a plurality of different expected signal levels. A set of default signal values may be used by the Viterbi Equalizer. The system is also configured to determine whether these default expected signal levels are acceptable by monitoring the incoming data bits. If it is determined that the actual signal levels of the incoming data bits differ from the default expected signal levels by more than a predetermined amount, the signal levels used by the Viterbi Equalizer may be changed from default signal levels to the adaptive signal levels. The adaptive signal levels may be determined using the synchronization pattern.
