Detector hardware complexity of high-order partial response magnetic read channels is a major obstacle to high data rate operation and reduced area and power consumption. The method presented here reduces the complexity of single-step and two-step implementations of the Viterbi detector by applying a distance-enhancing code that eliminates some states from(More)
Hardware complexity required for the implementation of EPR4 magnetic read channel results in slower operation and increased area and power consumption. The Viterbi sequence detector for EPR4 channel requires 16 states that could be realized as an array of 16 single step or twostep add-compare-select units. The method presented here reduces the complexity of(More)
