Study on Implementation of Traceback Algorithm in Viterbi Decoders
Viterbi译码器回溯算法实现研究

This paper discusses two traceback algorithms for Viterbi decoder. The realization methods for the traceback algorithms with FPGA are given through optimization for the hardware architecture. The comparison between the two realization methods is given. Finally, the two realization methods are applied to Viterbi decoder, and both simulation and hardware test show that the presented implementation methods are correct.
