A receiving apparatus comprising: a receiver configured to receive a signal from a transmitting apparatus; a demodulator configured to demodulate the signal to generate values according to 64-quadrature amplitude modulation, QAM; a deinterleaver configured to deinterleave the values; and a decoder configured to decode the deinterleave values based on a low density parity check code, LDPC, having a code rate being 3/15, wherein the demodulator is configured to demodulate the signal based on at least one constellation point among constellation points represented as a table below: 0.5472 + 1.1591i 0.5473 + 1.1573i 0.5467 + 1.1599i 0.5479 + 1.1585i 1.1578 + 0.5478i 1.1576 + 0.5475i 1.1591 + 0.5475i 1.1591 + 0.5475i 0.3163 + 0.5072i 0.3163 + 0.5072i 0.3163 + 0.5072i 0.3163 + 0.5072i 0.5087 + 0.3163i 0.5087 + 0.3163i 0.5087 + 0.3163i 0.5087 + 0.3163i -0.5472 + 1.1591i -0.5473 + 1.1573i -0.5467 + 1.1599i -0.5479 + 1.1585i -1.1578 + 0.5478i -1.1576 + 0.5475i -1.1591 + 0.5475i -1.1591 + 0.5475i -0.3163 + 0.5072i -0.3163 + 0.5072i -0.3163 + 0.5072i -0.3163 + 0.5072i -0.5087 + 0.3163i -0.5087 + 0.3163i -0.5087 + 0.3163i -0.5087 + 0.3163i -0.5472 - 1.1591i -0.5473 - 1.1573i -0.5467 - 1.1599i -0.5479 - 1.1585i -1.1578 - 0.5478i -1.1576 - 0.5475i -1.1591 - 0.5475i -1.1591 - 0.5475i -0.3163 - 0.5072i -0.3163 - 0.5072i -0.3163 - 0.5072i -0.3163 - 0.5072i -0.5087 - 0.3163i -0.5087 - 0.3163i -0.5087 - 0.3163i -0.5087 - 0.3163i 0.5472 - 1.1591i 0.5473 - 1.1573i 0.5467 - 1.1599i 0.5479 - 1.1585i 1.1578 - 0.5478i 1.1576 - 0.5475i 1.1591 - 0.5475i 1.1591 - 0.5475i 0.3163 - 0.5072i 0.3163 - 0.5072i 0.3163 - 0.5072i 0.3163 - 0.5072i 0.5087 - 0.3163i 0.5087 - 0.3163i 0.5087 - 0.3163i 0.5087 - 0.3163i a receiver configured to receive a signal from a transmitting apparatus; a demodulator configured to demodulate the signal to generate values according to 64-quadrature amplitude modulation, QAM; a deinterleaver configured to deinterleave the values; and a decoder configured to decode the deinterleave values based on a low density parity check code, LDPC, having a code rate being 3/15, wherein the demodulator is configured to demodulate the signal based on at least one constellation point among constellation points represented as a table below: 0.5472 + 1.1591i 0.5473 + 1.1573i 0.5467 + 1.1599i 0.5479 + 1.1585i 1.1578 + 0.5478i 1.1576 + 0.5475i 1.1591 + 0.5475i 1.1591 + 0.5475i 0.3163 + 0.5072i 0.3163 + 0.5072i 0.3163 + 0.5072i 0.3163 + 0.5072i 0.5087 + 0.3163i 0.5087 + 0.3163i 0.5087 + 0.3163i 0.5087 + 0.3163i -0.5472 + 1.1591i -0.5473 + 1.1573i -0.5467 + 1.1599i -0.5479 + 1.1585i -1.1578 + 0.5478i -1.1576 + 0.5475i -1.1591 + 0.5475i -1.1591 + 0.5475i -0.3163 + 0.5072i -0.3163 + 0.5072i -0.3163 + 0.5072i -0.3163 + 0.5072i -0.5087 + 0.3163i -0.5087 + 0.3163i -0.5087 + 0.3163i -0.5087 + 0.3163i -0.5472 - 1.1591i -0.5473 - 1.1573i -0.5467 - 1.1599i -0.5479 - 1.1585i -1.1578 - 0.5478i -1.1576 - 0.5475i -1.1591 - 0.5475i -1.1591 - 0.5475i -0.3163 - 0.5072i -0.3163 - 0.5072i -0.3163 - 0.5072i -0.3163 - 0.5072i -0.5087 - 0.3163i -0.5087 - 0.3163i -0.5087 - 0.3163i -0.5087 - 0.3163i 0.5472 - 1.1591i 0.5473 - 1.1573i 0.5467 - 1.1599i 0.5479 - 1.1585i 1.1578 - 0.5478i 1.1576 - 0.5475i 1.1591 - 0.5475i 1.1591 - 0.5475i 0.3163 - 0.5072i 0.3163 - 0.5072i 0.3163 - 0.5072i 0.3163 - 0.5072i 0.5087 - 0.3163i 0.5087 - 0.3163i 0.5087 - 0.3163i 0.5087 - 0.3163i
