摘要

A check matrix creation device includes a circulant permutation matrix setting unit 12 for preparing a plurality of circulant permutation matrices each having an inner diameter of six or larger, and a quasi-cyclic matrix creation unit 13 for arranging the plurality of circulant permutation matrices prepared by the circulant permutation matrix setting unit 12 both in a row direction and in a column direction to create a quasi-cyclic matrix.
