Title: PRE-DISTORTION PROCESSING METHOD AND APPARATUS
Abstract:
Provided are a pre-distortion processing method and apparatus. The apparatus comprises a first pre-distortion part and a second pre-distortion part, wherein the first pre-distortion part comprises N DPD processors, which perform pre-distortion processing on a signal by means of the first pre-distortion part and the second pre-distortion part, so as to support the linear amplification of the signal by a power amplifier. By means of the pre-distortion processing apparatus provided in the present application, the amplification efficiency of a power amplifier can be increased, the design complexity of the pre-distortion processing apparatus can be reduced, cost can be saved, and power consumption can be reduced.
