Abstract
A data error correction system, which is capable of executing repeated error correction processing, and which improves the quality of communication links by allowing repeated corrections of errors generated in the transmission line, comprises a Viterbi decoder for decoding a designated encoded data from a buffer and a block decoder for executing decoding of the data corresponding to a length of a block code after being decoded from the Viterbi decoder, when error correction is possible. The data error correction system controls execution of re-decoding by the Viterbi decoder for executing error correction of the data corresponding to a length of a block code whose correction has not been possible yet.
