Claim:
1. A full-duplex communication apparatus, comprising at least one transmit antenna and at least one signal synthesizing apparatus, wherein the signal synthesizing apparatus is connected to at least two receive antennas, and the at least one transmit antenna is configured to transmit a first transmit signal; the at least two receive antennas are configured to separately receive the first transmit signal as received first transmit signals; and the signal synthesizing apparatus is configured to receive the received first transmit signals from the at least two receive antennas, wherein a phase difference exists between the received first transmit signals, and synthesize the received first transmit signals, wherein a strength of a resulting synthesized first transmit signal is lower than a strength of at least one of the received first transmit signals received by the signal synthesizing apparatus, wherein: the at least two receive antennas are further configured to separately receive a first receive signal as received first receive signals, the signal synthesizing apparatus is further configured to receive the first receive signals from the at least two receive antennas and synthesize the received first receive signals, wherein a strength of a resulting synthesized first receive signal is higher than a strength of any one of the first receive signals received by the signal synthesizing apparatus, and wherein the at least one signal synthesizing apparatus specifically comprises at least two signal synthesizing apparatuses, and the full-duplex communication apparatus further comprises a second signal synthesizing apparatus, wherein the second signal synthesizing apparatus is connected to the at least two signal synthesizing apparatuses, and the second signal synthesizing apparatus is configured to receive residual first transmit signals from the at least two signal synthesizing apparatus and synthesize the received residual first transmit signals, wherein strength of the synthesized first transmit signal is lower than strength of at least one of the residual first transmit signals received by the second signal synthesizing apparatus.
