摘要：Embodiments of the present invention disclose a wireless communicationsmethod 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 thefirst radio frequency signal to a transmit antenna; then performing, under control of apre-generated control signal, phase adjustment and amplitude adjustment on the firstradio frequency signal and obtaining a cancellation signal; performing self-interferencecancellation on a second radio frequency signal received from a radio air interface byusing a receive antenna and the cancellation signal so as to generate a third radiofrequency signal obtained after self-interference cancellation; and finally demodulatingthe third radio frequency signal into a receive digital signal. According to theembodiments of the present invention, phase and amplitude adjustment may beperformed, according to a channel characteristic of a wireless self-interference channel,on a transmitted radio frequency signal so as to generate a cancellation signal, and self-interference cancellation is performed on a received radio frequency signal and thecancellation signal, which reduces interference of the sent radio frequency signal to thereceived radio frequency signal in a full-duplex communication mode, and improvesreliability of mobile communications.
