Efficient survivor memory management for the traceback method in viterhi decoders

Abstract

WR ",>.re I Abstract -Trucehack'schemes used in Viterhi decoders can he categorized inro multi-pointer and one-puinrer methods. A traceback scheme using one-pointer method has been shown to be better than the one using mtilli-pointer metl~od in terms of memo? size and latency. We propose an area &Yent tracehack method Mhicli i s based on the one-pointer scheme. Tlie proposed method can he implemented hy osing on/v two single-port meinor?, hanks. In comparison with traditional metl~ods. lowr power coiisamptiun and .smaller urea occtipafion are requiredfor the proposed metliod.
