Embodiments of the present invention provide a transmitter and an interference eliminating method. The transmitter provided by the embodiments of the present invention comprises: a feedback cancellation module, a first digital predistorter (DPD) and a power amplifier (PA). The feedback cancellation module is located on a feedback channel of the transmitter, and is respectively connected to the PA and the first DPD. The feedback cancellation module is used for performing interference cancellation on a signal over the feedback channel according to a feedback cancellation signal to obtain a first hybrid signal, and sending the first hybrid signal to the first DPD. The first DPD is used for performing linear predistortion processing according to the first hybrid signal and a first baseband signal on a first transmission channel to generate a first predistorted signal. The PA is used for amplifying a to-be-transmitted signal and transmitting the amplified signal through an antenna, the to-be-transmitted signal being the first predistorted signal or a signal obtained according to the first predistorted signal. By means of the embodiments of the present invention, the distortion of a transmitted signal is reduced. |
