Original Abstract Submitted
an ldpc encoder is described with memory for storing a parity check matrix and a calculation unit to encode information bits into a codeword with reference to the parity check matrix. the parity check matrix includes an information part matrix and a parity part matrix. in the parity part matrix, z*z sub-matrices are sub-matrices, other than a zero matrix, and are arranged in each of the m rows and m columns. a sub-matrix is a scaled cyclic matrix obtained by shifting elements of an identity matrix by one to the left and multiplying the shifted elements by a scaling element. except for the scaled cyclic matrix, the remaining sub-matrices are a zero matrix or an identity matrix, and the scaling element is an element allowing the parity part matrix to satisfy a full rank condition on a galois field.
