<p>A predetermined information length, a predetermined coding rate and a predetermined maximum order of the column are used to calculate parameters for a pseudo random number permutation matrix. The calculated parameters for the pseudo random number permutation matrix are used, with a pseudo random number sequence and a Latin square matrix, to produce the pseudo random number permutation matrix. A predetermined information length, a predetermined coding rate and a predetermined maximum order of the column are used to calculate parameters for possible order distribution combinations for optimizing the order distribution of production of a check matrix that can be constructed by use of the pseudo random number permutation matrix. The order distribution of the check matrix production is optimized with the calculated possible order distribution combinations used as forced conditions. The optimized order distribution of the check matrix production is used to arrange the produced pseudo random number permutation matrix to produce a check matrix to be used for low-density parity check codes.</p> |
