Abstract
An error correction encoding deviceincludes a sparse matrix computing unitthat computes exclusive OR of a submatrix, in a parity-check matrix, corresponding to an information bit sequence, and the information bit sequence on the basis of the position of 1 in the submatrix to calculate a vector, a fundamental matrix operatorthat calculates a predetermined matrix by performing a predetermined fundamental matrix operation on a submatrix, in the parity-check matrix, corresponding to a parity bit sequence, and a matrix multiplierthat calculates the parity bit sequence by multiplying the predetermined matrix which the fundamental matrix operatorcalculates, and the vector which the sparse matrix computing unitcalculates.
