METHOD AND DEVICE FOR INFORMATION PROCESSING AND COMMUNICATION DEVICE Russian patent published in 2018 - IPC H03M13/11 

Abstract RU 2667772 C1

FIELD: data processing.

SUBSTANCE: group of inventions refers to the field of coding. Method comprises: encoding an information bit sequence using a low density parity check matrix, an LDPC, the base LDPC graph of the matrix is represented as a matrix with m rows and n columns, m is an integer greater than or equal to 5, and n is an integer greater than or equal to 16; and the base graph includes the submatrix A and the submatrix B, the submatrix A being the matrix A0 or submatrix A includes the first 16 columns of the matrix A0, and the matrix A0 is a matrix with five rows and 22 columns; and the submatrix B is a matrix with five rows and five columns and the submatrix B includes one column whose weight is 3 and one submatrix B' of the bidiagonal structure.

EFFECT: technical result is to ensure the encoding of information bit sequences of a plurality of lengths.
