ABSTRACT:
A decoding apparatus includes simultaneous decoding means for sequentially Viterbi-decoding a plurality of data sequences over respective data lengths from the start at the same time, and stop means for sequentially comparing likelihoods of respective data sequences which are simultaneously Viterbi-decoded by the simultaneous decoding means and stopping the simultaneous decoding means from decoding a certain data sequence if it is determined based upon the compared result that a likelihood of the certain data sequence is lower than a threshold value.
