CODING DEVICE, ERROR-CORRECTION CODE CONFIGURATION METHOD AND PROGRAMME THEREFOR Russian patent published in 2014 - IPC H03M13/19 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to coding means. The coding device includes an inspection matrix generating module which generates a block inspection matrix; and a coding module which generates and outputs a code word from an input message through the inspection matrix. The inspection matrix generating module includes: a degree-allocation unit which prescribes function values of the block inspection matrix through coefficients of a self-dual polynomial expression; a weight distribution determination unit which prescribes the number of components that are non-zero matrices among the components of each block of the block inspection matrix using a mask pattern; a first degree-altering unit which considers the sum of the components of the k_r-th row block of the block inspection matrix as a cyclic permutation matrix; and a second degree-altering unit which prescribes the number of row-block components that are non-zero matrices among the components of each row block excluding said k_r-th row block of the block inspection matrix.

EFFECT: smaller storage region required to store multiple low-density parity-check codes.
