Abstract: Methods and apparatus for facilitating wireless communication using digital Quadrature Amplitude Modulation are disclosed. A mapping module electronic component of a wireless communication device utilizes a signal constellation for quadrature modulating a signal for transmission or quadrature demodulating a received signal. The signal constellation includes multiple constellation symbols and associated bit sequences. Specific signal constellations are disclosed. The signal constellations may be obtained through an optimization procedure which accounts for both phase noise and power amplifier nonlinearity.

Abstract: Embodiments of the present disclosure provide a signal processing method, an apparatus, and a system. The signal processing method includes acquiring a phase of each of transmit antennas when the lth OFDM data symbol is sent, and acquiring a phase of each of receive antennas when the lth OFDM data symbol is received. The method further includes compensating received signals of each of the receive antennas according to the phase of each of the transmit antennas when the lth OFDM data symbol is sent and the phase of each of the receive antennas when the lth OFDM data symbol is received, to obtain compensated signals of each receive antenna.
