Wireless communications method and system, and full-duplex wireless transceiver
Embodiments of the present invention disclose a wireless communications method and system, and a full-duplex wireless transceiver, where the method includes: modulating a transmit digital signal into a first radio frequency signal and outputting the first radio frequency signal to a transmit antenna; then performing, under control of a pre-generated control signal, phase adjustment and amplitude adjustment on the first radio frequency signal and obtaining a cancellation signal; performing self-interference cancellation on a second radio frequency signal received from a radio air interface by using a receive antenna and the cancellation signal so as to generate a third radio frequency signal obtained after self-interference cancellation; and finally demodulating the third radio frequency signal into a receive digital signal.
