Claim 4:
5. The method according to claim 1, wherein a transmit antenna and the receive antenna are not independent, the first self-interference reconstruction module comprises: a first reconstruction branch configured to reconstruct a self-interference component that enters the receive antenna through reflection, a second reconstruction branch configured to reconstruct a self-interference component that enters the receive antenna through leakage, and a combiner configured to combine reconstruction signals of the first and second reconstruction branches; and
the time reversal-filtered sending signal is divided into two signals using a power divider, the two signals respectively pass through the first reconstruction branch and the second reconstruction branch, to obtain the first-level self-interference reconstruction signal and the second-level self-interference signal, and the first-level self-interference reconstruction signal and the second-level self-interference signal are combined using the combiner.
