1. A method, comprising:
determining, by a processor of an apparatus, a first base matrix corresponding to a parity-check matrix of Low-Density Parity-Check (LDPC) code;
determining, by the processor, a plurality of second base matrices based on the first base matrix by shifting elements of a first row of the first base matrix along row-direction, shifting elements of a first column of the first base matrix along column-direction, and shifting elements outside the first row and the first column of the first base matrix along both column-direction and row-direction, wherein a value of each element is one;
determining, by the processor, the parity-check matrix according to the first base matrix and the second base matrices; and
transceiving, by the processor, a message, which is encoded by the parity-check matrix, with a network node.
