Disclosed in the embodiment are a self-interference elimination device and method, the method comprising: eliminating self-interference with respect to a low-frequency signal after converting a received radio-frequency signal to a low-frequency signal. Compared to self-interference elimination of a radio-frequency signal in the prior art, it is simpler and more feasible to eliminate self-interference on the low-frequency band, i.e., only using a mixer circuit and a self-interference elimination circuit, without using a large device such as a circulator, facilitating integration into a chip, and thereby reducing the volume of the self-interference elimination device. |
