<p><P>PROBLEM TO BE SOLVED: To provide an easily realizable digital broadcast channel decoding apparatus and a digital broadcast channel-decoding method therefor. <P>SOLUTION: The channel-decoding apparatus includes a depuncturing part (340) for inserting an arbitrary value to the punctured position of input data, on the basis of a puncturing pattern and outputting depuncturing data, a Viterbi decoder for decoding the depuncturing data to output decoded data, temporarily storing and reading the depuncturing data and the puncturing pattern, and a performance-measuring part (360) for utilizing the decoded data and the puncturing pattern, to calculate the error rate of the decoded data. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
