摘要：
The invention discloses an error-correcting apparatus for decoding an input signal by using a Viterbi algorithm to generate a Viterbi-decoded signal, including an erasure unit and a decoder. The erasure unit is configured to generate at least one logic signal according to at least one path metric difference of path metrics in the Viterbi algorithm, and generate erasure information, wherein the erasure information indicates data reliability of at least one location of the Viterbi-decoded signal. The decoder is configured to decode the Viterbi-decoded signal according to the erasure information.
