摘要： A method for generating a parity check matrix of a Low Density Parity Check (LDPC) code. A base matrix is generated in which elements with a value of 1 are arranged at predefined distances. The elements with the value of 1 in the base matrix are replaced with predefined sub-matrices. The method can improve the performance of the LDPC code by implementing the parity check matrix in which the number of 4-cycles or 6-cycles adversely affecting the LDPC code performance is minimized.
