  • Apparatus and method for encoding low density parity check codes in a communication system
    Patent number: 7930619
    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.
    Type: Grant
    Filed: April 26, 2007
    Date of Patent: April 19, 2011
    Assignees: Samsung Electronics CO., Ltd., Seoul National University Industry Foundation
    Inventors: Dong-Joon Shin, Yong-Chun Piao
