Summary:The invention discloses short code length LDPC (Low Density Parity Check), a coder, a decoder and a coding method based on quasi-cyclic. A codon structure is H=[H'1 II P'], wherein H'1 is an information bit matrix, P' is a check bit matrix, and II P' is row transformation of the check bit matrix. The information bit matrix H'1 comprises a plurality of cyclic submatrixes pi, j, and each cyclic submatrix can only be a unit cyclic bias matrix or a zero matrix. According to the technical scheme, a lot of analogue simulations are performed, so as to find an LDPC codon information bit matrix structure which is more suitable for an HSS (horizontal shuffle scheduling) decoding algorithm, and the coder and decoder using LDPC codes, thereby improving LDPC codon performance.
