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.
