Transmitting method, receiving method, receiving apparatus and transmitting apparatus

A receiving method comprising:

• receiving a modulated signal;
• generating a baseband signal from the received modulated signal;
• generating encoded data configured by a plurality of bits in a symbol corresponding to the baseband signal;
• generating decoded data configured by a plurality of bits by decoding the encoded data, wherein:
• the symbol corresponding to the baseband signal being generated by using QPSK or 16QAM, and whichever of the QPSK or the 16QAM is used, specific two bits extracted from a plurality of bits configuring each of the symbols are bits belonging to specific encoded data;
• and
• the specific encoded data is LDPC encoded data.

A transmitting apparatus comprising:

• an encoding section that generates encoded data configured by a plurality of bits by encoding transmit data configured by a plurality of bits;
• a modulation section that generates a baseband signal corresponding to a symbol by modulating the encoded data;
• and
• a radio section that transmits a transmit signal based on the baseband signal, wherein:
• the encoded data being modulated by using QPSK or 16QAM, and whichever of the QPSK or the 16QAM is used, the modulation section generates the symbol in which specific two bits extracted from a plurality of bits configuring the symbol are bits belonging to specific encoded data;
• and
• the specific encoded data is LDPC encoded data.
