IN-BYTE PLURAL SPOTTY BYTE ERROR CORRECTION/DETECTION METHOD AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an in-byte plural spotty byte error correction/detection device equipped with a function for controlling a multiple in-byte plural spotty byte error. SOLUTION: There is provided the in-byte plural spotty byte error correction/detection device equipped with an encoding means for producing transmission words based on input information data and a decoding means for entering, as reception words, the transmission words in which an error has been generated in an information transmission channel to correct or detect the error. In the in-byte plural spotty byte error correction/detection device, the encoding means produces the transmission words by adding check information produced based on a parity check matrix for expressing spotty byte error control signs and the input information data to the input data. The decoding means is equipped with a syndrome producing means for producing the syndrome of the reception words based on the parity check matrix and an error correcting means for correcting or detecting the error of the reception words based on the syndrome produced by the syndrome producing means.
