CHECK MATRIX GENERATING METHOD |
摘要 |
An irregular parity check matrix is generated which has an LDGM structure in which a masking quasi-cyclic matrix and a matrix in which cyclic permutation matrices are arranged in a staircase manner are arranged in a predetermined location. A mask matrix capable of supporting a single encoding rate for making the regular quasi-cyclic matrix into an irregular quasi-cyclic matrix is generated. The irregular parity check matrix is masked using a generated mask matrix, and a parity check matrix is generated combining a masked irregular parity check matrix with a lower triangular matrix formed in a staircase manner to satisfy a single encoding rate.
