1. A method for digital communications, comprising:

  • obtaining a code block size for Low Density Parity Check (LDPC) coding;

    determining a coding expansion factor z from a set of coding expansion factors based on the code block size and a parameter kb associated with a basic check matrix, wherein the set of coding expansion factors includes a set of natural numbers; and

    encoding or decoding a data sequence based on the basic check matrix and the coding expansion factor z,wherein the parameter kb and the coding expansion factor z are integers larger than 1, and wherein the basic check matrix has mb rows and nb columns, and wherein kb is equal to nb minus mb.
