Abstract: A pre-distortion coefficient corresponding to a transmit power currently set by a transmitting end is adjusted. A signal received quality report which is obtained according to the pre-distortion coefficient before adjustment is analyzed and fed back by a receiving end and a signal received quality report that is obtained according to the pre-distortion coefficient after adjustment and fed back by the receiving end. The analysis determines a variation situation of signal received quality of the receiving end. If the signal received quality of the receiving end becomes better, the pre-distortion coefficient after adjustment is used as the pre-distortion coefficient corresponding to the transmit power currently set by the transmitting end. The process then returns to the step of adjusting a pre-distortion coefficient corresponding to a transmit power currently set by a transmitting end.
