Co-time co-frequency full duplex terminal sharing antenna in receiving and transmitting and communication method therefor

Disclosed are a co-time co-frequency full duplex terminal sharing an antenna in receiving and transmitting and a communication method therefor. The terminal comprises: a transmitting module for outputting a transmitting signal to an antenna module after power amplification is performed on a radio frequency signal obtained through modulation by a radio frequency transceiver; the antenna module for receiving a base station signal and combining same with a self-interference signal to form a mixed signal; and a receiving module for processing the transmitting signal to generate a sampling signal, delaying the mixed signal and then performing mixed interference cancellation on same and the sampling signal.
