Classification: CPC H | IPC H

Claim 8:
9. The method according to claim 1, wherein the first transmit signal comprises a first carrier signal and a second carrier signal, and a center frequency of the second carrier signal is higher than a global system for mobile communications (GSM)/long term evolution (LTE) interfering frequency; the second carrier signal generates self-interference noise at the receive end of the first device; the second signal further comprises the self-interference noise; and the method further comprises:
reconstructing, by the first device, the self-interference noise based on the first transmit signal and a second interference cancellation error reference value, to obtain a cancellation signal of the self-interference noise; and
canceling, by the first device, the self-interference noise from the second receive signal based on the cancellation signal of the self-interference noise.
