摘要:
A received data decoding apparatus receives and decodes transmitted convolutional code data. The received data is formed of a first channel whose data rate is fixed and a second channel whose data rate is variable. The received data decoding apparatus includes a most likelihood decoder for decoding the received data on the basis of a Viterbi algorithm and a data rate decision unit for obtaining a predetermined data rate of the second channel determined according to a path metric amount which is a decoded output from the most likelihood decoder.
