Claim Text:
1. A method for transmitting a signal by a transmitting apparatus in a wireless communication system supporting a hybrid frequency shift keying (FSK) and quadrature amplitude modulation (QAM) modulation (FQAM) scheme, the method comprising: determining, by the transmitting apparatus, at least one first bit to map to at least one QAM symbol and at least one second bit to map to at least one FSK symbol among bits in an encoded binary bit stream; generating, by the transmitting apparatus, a FQAM modulation symbol by mapping the at least one first bit to the at least one QAM symbol and mapping the at least one second bit to the at least one FSK symbol, and transmitting, by the transmitting apparatus, the signal that is based on the generated FQAM modulation symbol.
