Abstract :
This work extends previous trace-back approaches. A new one-pointer trace-back algorithm for survivor sequence memory management that is particularly well-suited to a VLSI implementation is described. Memory size, latency and implementational complexity of the survivor sequence management are analyzed for both uniprocessor and multiprocessor realizations of Viterbi decoders
