Disclosed are a wireless communication method and system, and a full-duplex wireless transceiver. The method comprises: after a transmit digital signal is modulated into a first radio-frequency signal, outputting the first radio-frequency signal to a transmit antenna, then performing phase adjustment and amplitude adjustment on the first radio-frequency signal under the control of a pre-generated control signal, and acquiring a cancellation signal, perform self-interfering cancellation on a second radio-frequency signal received by a receiving antenna from a wireless air interface and the cancellation signal so as to generate a third radio-frequency signal after self-interfering cancellation, and finally demodulating the third radio-frequency signal into a receiving digital signal. In the embodiments of the present invention, phase and amplitude adjustment may be performed on a transmitted radio-frequency signal according to the channel characteristics of a wireless self-interfering channel so as to generate a cancellation signal, and a received radio-frequency signal performs self-interfering cancellation with the cancellation signal, which reduces the interference imposed by the transmitted radio-frequency signal on the received radio-frequency signal under a full-duplex communication mode, and improves the reliability of mobile communications. |
