Abstract
The authors propose an efficient traceback scheme for the parallel har dware implementation of the Viterbi algorithm. Compared to the convent ional Viterbi algorithm, where output is selected arbitrarily when mul tiple survivor paths exist, the proposed algorithm decides decoding ou tput by analysing the survivor paths of consecutive tracebacks. Experi mental results show that the proposed algorithm exhibits improved erro r-correction capability compared to the existing algorithms.
