Abstract: A digital pre-distortion method for a multiband signal, an electronic device and a non-transitory computer-readable storage medium are disclosed. The digital pre-distortion method may include: determining a possible power amplifier distortion according to configuration of a signal issued by a cell; selecting a basis function of pre-distortion according to the possible power amplifier distortion; solving, according to a pre-collected reference multiband signal and a corresponding feedback signal, the selected basis function to obtain a pre-distortion parameter; and processing an input multiband signal according to the selected basis function and the pre-distortion parameter to generate a pre-distortion signal.
