DEVICE AND METHOD FOR ELIMINATING SELF-INTERFERENCE SIGNAL

摘要

The present invention relates to the technical field of wireless communications. Disclosed are a device and a method for eliminating a self-interference signal. The device comprises a first self-interference eliminating unit, the first self-interference eliminating unit being used to perform coupling by using a transmitted signal output by an analog transmission processing module, to obtain a first analog signal; perform an analog-to-digital conversion on the first analog signal, to obtain a first digital signal; perform interference reestablishment according to the first digital signal, to obtain a first digital interference elimination signal; eliminate, according to the first digital interference elimination signal, a self-interference signal comprised in a digital signal output by a first analog-to-digital conversion module, to obtain a first output signal, and transmit the first output signal to a digital receiving processing module. The present invention eliminates, by using a first digital interference elimination signal, interference from a digital signal output by a first analog-to-digital conversion module, thereby eliminating a self-interference signal in a transmit process.
