    摘要： A method and apparatus for generating Low-Density Parity Check (LDPC) codes of various block lengths from a structured LDPC code in a communication system is provided. To support various block lengths, predefined rules are applied to a parity check matrix of an LDPC code, and then shortening is selectively applied to the parity check matrix. Subsequently, if information data bits are input, the input data information bits are encoded into an LDPC codeword by using the parity check matrix according to a preset encoding scheme, and then the encoded LDPC codeword is transmitted after puncturing is selectively applied.

    摘要： An apparatus and method for encoding a channel in a communication system using a Low-Density Parity-Check (LDPC) code. The method includes determining a number of parity bits to be subjected to puncturing; dividing the parity bits at predetermined intervals, and determining a number of puncturing bits, which are subjected to puncturing within the predetermined intervals; determining positions of puncturing parity bits corresponding to the determined number of puncturing bits; and repeatedly performing puncturing on the puncturing parity bits corresponding to the determined positions at the predetermined intervals. The predetermined intervals are determined by dividing a length of parity bits by a length of one column group in a parity-check matrix.
