Classification: CPC H | IPC H

Claim 0:
1. A transmitting method comprising:
filling information bits with input bits and one or more zero padding bits, if a size of the input bits is less than a size of the information bits;
encoding the information bits to generate parity bits based on a low density parity check (LDPC) code, a code rate of the LDPC code being 3/15 and a code length of the LDPC code being 16200 bits;
splitting a codeword comprising the information bits and the parity bits into a plurality of bit groups;
interleaving bit groups including the parity bits among the plurality of bit groups based on a permutation order to provide an interleaved codeword;
calculating a number of parity bits to be punctured;
puncturing one or more parity bits of the interleaved codeword based on the calculated number;
mapping the input bits and remaining parity bits of the interleaved codeword after the puncturing to constellation points for quadrature phase shift keying (QPSK); and
transmitting a signal which is generated based on the constellation points,
wherein bits of 20th, 24th, 44th, 12th, 22nd, 40th, 19th, 32nd, 38th, 41st, 30th, 33rd, 14th, 28th, 39th and 42nd bit groups among the plurality of bit groups are punctured.
