Abstract
A method includes: A first device sends a first signal to a second device, where the first signal includes a first transmit signal and a first pilot signal; the first device obtains a second signal, where the second signal includes a first self-interference signal, a second pilot signal, and a second receive signal from the second device; the first device extracts jitter information of the first self-interference signal based on the first pilot signal and the second pilot signal; the first device reconstructs a self-interference signal based on the first transmit signal and the jitter information of the first self-interference signal, to obtain a cancellation signal of the first self-interference signal; and the first device cancels the first self-interference signal from the second receive signal based on the cancellation signal of the first self-interference signal.
