decoders
Key words: VLSI, Viterbi algorithm, Trace-Back, Exchange Register
Abstract:
The management of the surviving path memory in Viterbi's algorithm is generally performed by Trace-Back or
Exchange.Register. A generalized method using precompiled trace-backs is presented. Resolution by a graphical method is proposed
and three examples are solved.
