ABSTRACT:
A Low Density Parity Check (LDPC) code encoding apparatus for a communication system is provided. The encoding apparatus receives information bits, and generates an LDPC code by encoding the information bits using an interleaving scheme. The interleaving scheme is generated such that when the LDPC code is punctured, there is no short-length cycle in a Tanner graph of the punctured LDPC code.
