摘要：The present invention relates to the field of wireless communicationstechnologies, and discloses a self-interference signal cancellation device and method.The device includes a first self-interference cancellation unit, where the first self-interference cancellation unit is configured to: obtain a first analog signal by coupling atransmit signal output by an analog transmit processing module; perform analog-to-digital conversion on the first analog signal, to obtain a first digital signal; performinterference reconstruction according to the first digital signal, to obtain a first digitalinterference cancellation signal; and cancel, according to the first digital interferencecancellation signal, a self-interference signal included in a digital signal output by a firstanalog-to-digital conversion module, to obtain a first output signal, and output the firstoutput signal to a digital receive processing module. In the present invention, afterinterference cancellation is performed by using the first digital interference cancellationsignal and the digital signal output by the first analog-to-digital conversion module, aself-interference signal introduced during transmission can be canceled.
