Abstract
A data detector includes a branch metric calculator operable to calculate branch metrics for transitions between states in a trellis for the data detector, and a pruning circuit operable to prune prohibited states from the trellis. The states in the trellis comprise basic states and extended states, where the extended states have a greater number of bits than the basic states.
