1. A non-transitory computer program product comprising programming instructions stored in a computer readable storage medium for enabling a computer to perform operations comprising:
performing, based on a first check matrix, low-density parity-check (LDPC) code encoding on an information bit sequence to obtain a first codeword at a first code rate, wherein:
the first check matrix is obtained by reading i rows and j columns from a mother matrix, and
the mother matrix comprises: a basic matrix, an extension matrix, a first fixed matrix, and a second fixed matrix;
and
sending the first codeword.
