1. A receiving method comprising:
demodulating a signal received from a transmitting apparatus to generate values based on 1024-quadrature amplitude modulation (QAM);
splitting the values into a plurality of groups;
deinterleaving the plurality of groups based on an interleaving order; and
decoding values of the deinterleaved plurality of groups based on a low density parity check (LDPC) code, a code rate of the LDPC code being 6/15 and a code length of the LDPC code being 64800,
wherein the plurality of groups are deinterleaved based on a following equation:
Yπ(j)=Xj for(0≤j<Ngroup),
where Xj is a j-th group among the plurality of groups, Yj is a j-th group among the deinterleaved plurality of groups, Ngroup is a number of the plurality of groups, and π(j) denotes the interleaving order, and
wherein the π(j) is represented as follows:
