Abstract: A wireless communication with modulation and demodulation set based on channel information is disclosed. An operating method of a first wireless communication device includes: transmitting a pilot signal via a wireless channel to a second wireless communication device; receiving channel state information, estimated by and transmitted from the second wireless communication device in response to the pilot signal, the channel state information including amplitude information and phase information of a wireless channel; setting a modulation method for data transmission based on the amplitude information and the phase information of the wireless channel; generating modulated data based on the modulation method; and transmitting the modulated data via the wireless channel.
