Abstract
A Viterbi decoding apparatus includes a main decoder, a re-encoder, an adjusting module, a secondary decoder and a secondary result generating module. The main decoder performs a Viterbi decoding process on input data to generate a set of main decoded results. The re-encoder performs a convolutional encoding process on the set of main decoded results to generate a set of re-encoded results. The adjusting module adjusts the input data according to the set of re-encoded results to generate adjusted input data corresponding to a predetermined path in a Viterbi trellis diagram. The secondary decoder generates a plurality of symbols according to the adjusted input data. The secondary result generating module generates a set of secondary decoded results according to the plurality of symbols and the set of main decoded results.
