Abstract
Embodiments of the present invention provide a digital predistortion processing method and a user terminal, which relate to the field of communications, and can simplify the structure of a digital predistortion apparatus and reduce the cost. The method includes: setting a control command; and tuning, when the control command is selecting a data collection mode as the working mode of a receive channel, the frequency of a local oscillator and the central frequency of a band-pass filter in the receive channel to the transmitting frequency of the user terminal, so that the user terminal performs predistortion factor update. The embodiments of the present invention are applied to the user terminal for digital predistortion processing.
