Abstract:
1. A method of encoding input information based on an LDPC (Low Density Parity Check), the method comprising: receiving information; and encoding the input information with an LDPC codeword using a parity check matrix, wherein the parity check matrix includes a first matrix, a dual diagonal matrix which has the same number of rows and columns as the number of rows of the first matrix, a zero matrix which has the same number of rows as the number of columns of the dual diagonal matrix, a second matrix which has the same number of rows as the number of the columns of the zero matrix, and an identity matrix which has the same number of rows and columns as the number of the columns of the zero matrix, wherein a last column of the first matrix is adjacent to a first column of the dual diagonal matrix in the parity check matrix, a last row of the first matrix and a last row of the dual diagonal matrix are adjacent to a first row of the second matrix in the parity check matrix, and wherein an element matrix of the dual diagonal matrix constituting a dual diagonal line is continuous to an element matrix that constitutes a diagonal line of the identity matrix.
