This invention discloses a for digital pre-distortion processing method and apparatus, the method including that: training signals are sent to at least one radio frequency front-end device as needed (201); the output training signals of the radio frequency front-end devices are collected through a feedback channel as needed (202); digital pre-distortion (DPD) coefficients of the radio frequency front-end devices are trained as needed (203); after the coefficient training is completed, the DPD coefficients of the corresponding radio frequency front-end devices are updated as needed. There is no need to track the variation of the signals all the time and to compare the signals with a long-time statistical signal template to trigger the training in the invention. The invention can accommodate a multi-antennas application without configuring a corresponding digital pre-distortion feedback channel and coefficient training module separately for each antenna, thereby when the antennas are increased, the volume and cost are not increased and the invention can be of good feasibility from the perspective of commercialization.
