摘要

A turbo decoding device for performing decoding on 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, comprising:
a memory operable to perform interleaving or deinterleaving in the decoding process; and a rewriting unit operable to rewrite likelihoods stored in the memory for data blocks that were evaluated as having no errors in the decoding process through error detection processing.
