摘要:
A method of encoding input data using a low density parity check (LDPC) code or decoding the encoded data is disclosed. Each index of a model matrix is expanded to an index matrix which includes two or more indexes. Each index included in the index matrix indicates a specific sub-matrix, and can be replaced with a corresponding sub-matrix to generate a parity check matrix.
