Disclosed are a multi-band broadband DPD lookup table generation method, a DPD processing method and system. The DPD lookup table generation method comprises: inputting a first-band training signal and a second-band training signal, and capturing feedback signals of the first-band training signal and the second-band training signal; training a first-band DPD coefficient according to the feedback signal of the first-band training signal, a reference signal and the feedback signal of the second-band training signal; training a second-band DPD coefficient according to the feedback signal of the second-band training signal, a reference signal and the feedback signal of the first-band training signal; and generating a first-band lookup table according to the trained first-band DPD coefficient, and generating a second-band lookup table according to the trained second-band DPD coefficient. The present invention can be adopted to solve the problem of restrictions to the implementation of hardware for multi-band broadband DPD processing in the prior art. |
