<p>A turbo coding device and turbo decoding device that allow for the presence of interleaving in the error correction coding process improves error correction capability even when the decoding device does not employ a scheme whereby extrinsic information is circulated as in a turbo decoding device. A turbo decoding device for decoding data that is obtained by performing error detection coding on a plurality of data blocks and further subjecting that data to turbo coding that includes interleaving in the coding process, comprises a rearrangement unit (18) operable to perform interleaving between a first decoding (16) a second decoding (21), an error detection unit (25) operable to perform error detection processing for each block based on data after the first decoding, and an adjustment unit (26) operable to adjust a likelihood indicated by data obtained after decoding in the first decoder but prior to the interleaving and corresponding to blocks evaluated as having no errors by the error detection unit, so as to increase reliability of the data.</p> |
