Abstract
The present invention provides a coding device of a low-density parity-check (LDPC) code for simply coding information data without generating a code generator matrix. The coding device forms a parity-check matrix having two sub-matrixes. At this time, the first sub-matrix is a random matrix or a structural matrix. The second sub-matrix is a structural matrix having two 1s in each column. Parity data is calculated by using the structural second matrix without calculating an inverse matrix of the second matrix when temporary data is generated by using the first sub-matrix with reference to the information data. Code data is generated from the parity data and the information data and is transmitted.
