Abstract

padthpadstThe present invention relates to performing shortening or puncturing when performing encoding or decoding through the use of a parity check matrix in a communication/broadcasting system. The operation method of a transmission terminal includes the steps of: determining the number of bits to be 0 padded; determining the number N of bit groups of which all bits are to be 0 padded; padding all bits within 0 to N 1 bit groups indicated by a shortening pattern with 0; mapping information bits to the locations of bits which are not padded in Bose Chaudhuri Hocquenghem (BCH) information bits; BCH encoding the BCH information bits in order to generate Low Density Parity Check (LDPC) information bits; and LDPC encoding the LDPC information bits in order to generate an O padded codeword. Here the shortening pattern is defined in the order of bit groups which are defined to be 9 8 15 10 0 12 5 27 6 7 19 22 1 16 26 20 21 18 11 3 17 24 2 23 25 14 28 4 13 and 29.
