1. A receiving method comprising:
demodulating a signal received from a transmitting apparatus based on an orthogonal frequency division multiplexing (OFDM) scheme;
demodulating the demodulated signal to generate values;
deinterleaving the values; and
decoding the deinterleaved values based on a low density parity check (LDPC) code, a code rate of the LDPC code being 4/15,
wherein the demodulated signal is demodulated based on constellation points for 64-quadrature amplitude modulation (QAM), and
wherein the constellation points comprise constellation points represented as below:
