1. A transmitting method comprising:
interleaving a codeword comprising input bits and parity bits;
mapping bits of the interleaved codeword to constellation points for 1024-quadrature amplitude modulation (QAM); and
transmitting a signal which is generated based on the constellation points,
wherein the parity bits are generated by encoding the input bits based on a low density parity check (LDPC) code, a code rate of the LDPC code being 4/15, and
wherein each of the constellation points is represented as one of A+Bi, −A+Bi, A−Bi and −A−Bi,
wherein A is a real component, B is an imaginary component, and each of A and B comprises one of values listed below:
