1. A transmitting method comprising:
generating a codeword comprising information bits and parity bits, wherein the parity bits are generated by encoding the information bits based on a low density parity check (LDPC) code, a code rate of the LDPC code being 5/15 and a code length of the LDPC code being 16200 bits;
splitting the codeword into a plurality of bit groups;
interleaving the plurality of bit groups to provide an interleaved codeword;
mapping bits of the interleaved codeword to constellation points for 16-quadrature amplitude modulation (QAM); and
transmitting a signal carrying the constellation points,
wherein the plurality of bit groups are interleaved based on a following equation:
Yj=Xπ(j) for (0≤j<Ngroup),
where Xj is a jth bit group among the plurality of bit groups, Yj is a jth bit group among the interleaved plurality of bit groups, Ngroup is a number of the plurality of bit groups, and π(j) denotes an interleaving order for the interleaving, and
wherein the π(j) is represented as follows:
