Decoding apparatus and method in a communication system using low density parity check codes |
摘要 |
A decoding method in a communication system using a Low Density Parity Check (LDPC) code. The method includes determining whether an LDPC codeword to be decoded is a general LDPC codeword to which a puncturing scheme is not applied or a punctured LDPC codeword to which the puncturing scheme is applied; if the LDPC codeword to be decoded is the punctured LDPC codeword, generating a child parity check matrix according to a mother parity check matrix indicative of a parity check matrix of the general LDPC codeword, and a puncturing pattern applied to the punctured LDPC codeword; and decoding the punctured LDPC codeword according to the child parity check matrix.
