According to a signal restoration method and a signal transceiver device provided in embodiments of the present invention, a first signal is converted into an equi-amplitude phase-inverted signal of the first signal, and the equi-amplitude phase-inverted signal of the first signal is used to restore a wanted signal from received signals; or a signal is transmitted by using a transmit antenna if a transmit party for a wanted signal does not transmit the wanted signal, a model of an interference channel is obtained by means of estimation, and a first signal is reconstructed according to the model, so as to restore the wanted signal from received signals. The first signal is an interference signal that is formed from a signal transmitted by the signal transceiver device and causes interference to the wanted signal received by the signal transceiver device. It can be learned that, according to the method and the signal transceiver device in the embodiments, interference caused by the signal transmitted by the signal transceiver device to the wanted signal received by the signal transceiver device can be canceled. Therefore, if one frequency is used to receive and transmit a signal, interference caused by a transmit signal to a receive signal can be avoided after a time interval is shortened or even without a time interval, so that a delay in a communication process can be reduced. |
