Title:
FULL-DUPLEX DIGITAL SELF-INTERFERENCE CLEAR METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/050717
Kind Code:
A1
Abstract:
Provided in the present disclosure is a full-duplex digital self-interference clear method, comprising: before signal transmission with a peer device is performed in a full-duplex manner, calculating a pre-distortion processing coefficient by using an adaptive algorithm and according to a preamble sequence that is sent by a sending link, a first interference signal that is generated by the preamble sequence for a receiving link, and a first reconstructed interference signal that is reconstructed by means of performing pre-distortion processing on the preamble sequence; when signal transmission with the peer device is performed in the full-duplex manner, performing, according to the pre-distortion processing coefficient, pre-distortion processing on a first signal that is sent to the peer device by the sending link, so as 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 receiving link, wherein the second interference signal is a signal that is obtained after an interference signal that is generated by the first signal for the receiving link and a second signal that is sent by the peer device and received by the receiving link are superimposed. Also provided in the present disclosure is a full-duplex digital self-interference clear apparatus.
