This invention discloses a method and device for digital pre-distortion processing, the method including that: as required, training signals are sent to at least one radio frequency front-end device (201); as required, the output training signals of the radio frequency front-end devices are collected through a feedback channel (202); as required, digital pre-distortion (DPD) coefficients of the radio frequency front-end devices are trained (203); after the coefficient training is completed, as required, the DPD coefficients of the corresponding radio frequency front-end devices are updated. There is no need to track the variation of the signals all the time and compare with a long-time statistical signal template to trigger the training in the invention. The invention can satisfy 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 realized easily viewed from the aspect of production. |
