APPARATUS AND METHOD FOR ENCODING AND DECODING CHANNEL IN A COMMUNICATION SYSTEM USING LOW-DENSITY PARITY-CHECK CODES
摘要
An apparatus and method for generating a parity-check matrix of a Low-Density Parity-Check (LDPC) code are provided. Parameters for designing the LDPC code are determined, and a first parity-check matrix of a quasi-cyclic LDPC code is formed according to the determined parameters. A second parity-check matrix is created through the elimination of a predetermined portion of a parity part in the first parity-check matrix, and a third parity-check matrix is created by rearranging the second parity-check matrix.
