  • Decoding method, decoding device, interleaving method, and transmitter
    Patent number: 8286050
    Abstract: A decoding device allowing a high-speed decoding operation. In a decoding section (215), if a degree of a check equation by a check matrix is D and the relationship between the check equation of the j+first row of the check matrix and the check equation of the jth row is shifted by n-bit, row processing operation sections (405#1 to 405#3) and column processing operation sections (410#1 to 410#3) perform the operation of a protograph in which the columns of the check matrix are delimited for each “(D+1)×N (N: natural number),” and the rows of the check matrix are delimited for each “(D+1)×N/n,” and formed as the processing unit of the row processing operation and column processing operation.
