Abstract
According to an embodiment, in a parity check matrix creation method, all N column vectors in the mask matrix are different. A submatrix having M rows×L columns obtained by arbitrarily extracting L continuous columns from the mask matrix includes Bfirst correction rows and Bith correction rows. The Bfirst correction rows have at least one '1' in total in each of Afirst correction columns. Each of the Bith correction rows has at least one '1' in total in A(i−1)th correction columns and has “1” in one of Aith correction columns included in a column set excluding the first correction columns to (i−1)th correction columns. The Bith correction rows include at least one “1” in total in each of the Aith correction columns. A sum from Ato Aequals L.
