Implementing reduced-state viterbi detectors |
摘要 |
A method of design and an implementation system for reduced-state Viterbi detectors for intersymbol interference channels are provided. The method uses a complement states grouping technique that comprises the steps of finding the state distances between complement states; forming the reduced-state trellis by grouping the complement states with state distance no less than the minimum free distance; and by keeping the complement states with state distance less than minimum free distance unchanged. The resultant reduced-state Viterbi detector has negligible performance loss compared to the full-state Viterbi detector while the complexity is reduced by a factor of about two.
