Abstract
The present disclosure provides a full-duplex digital self-interference clear method, including: before a signal is transmitted with a peer device in a full-duplex mode, performing a calculation by a self-adaptive algorithm to obtain a pre-distortion processing coefficient; under the condition that the signal is transmitted with the peer device in the full-duplex mode, performing pre-distortion processing on a first signal sent by the transmit link to the peer device according to the pre-distortion processing coefficient to obtain a second reconstructed interference signal; and performing self-interference clear according to the second reconstructed interference signal and a second interference signal of the receive link, with the second interference signal being a signal obtained through superimposition of an interference signal generated by the first signal in the receive link and a second signal received by the receive link from the peer device. The present disclosure further provides a full-duplex digital self-interference clear apparatus.
