Claim 11:
12. The method according to claim 1, wherein the first transmit signal generates the first self-interference signal to the receive end of the first device by generating a third self-interference signal to the receive end of the first device, wherein the third self-interference signal comprises the first self-interference signal; and
obtaining, by the first device, the second signal comprises:
obtaining, by the first device, a third signal, wherein the third signal comprises the second pilot signal, the second receive signal, and the third self-interference signal;
reconstructing, by the first device, a fourth self-interference signal based on the first transmit signal and a third interference cancellation error reference value, to obtain a cancellation signal of the third self-interference signal; and
canceling, by the first device, the third self-interference signal from the second receive signal based on the cancellation signal of the third self-interference signal, to obtain the second signal.
