Method and apparatus for channel coding and decoding in a communication system using a low-density parity-check code

摘要

An apparatus and method are provided for channel coding in a communication system using a Low-Density Parity-Check (LDPC) code. The method includes determining degrees for each of a plurality of column groups of an information part; determining a shortening order based on the degrees; generating a parity check matrix based on the shortening order; and performing coding using the parity check matrix.
