APPARATUS AND MATHOD FOR ENCODING LOW DENSITY PARITY CHECK CODE
摘要
PURPOSE: An apparatus and a method for encoding a low density parity check code are provided to generate a low density parity code having a low error by performing encoding of the low density parity code. CONSTITUTION: A parity check matrix generating part(310) generates a parity check matrix including a parity sub matrix. The parity check matrix includes a matrix element which is a message bit and a matrix element which is a parity bit. A puncturing part(320) performs puncturing about at least one matrix element among matrix element of a parity sub matrix. The puncturing part performs puncturing about at least one matrix element among matrix element of a first block matrix according to a puncturing order. The puncturing part punctures the matrix element of the first block matrix based on a matrix size of the first block matrix in a puncturing process. An encoding part(330) encodes an information word inputted from user by using the parity check matrix.
