Document Type and Number:
WIPO Patent Application WO/2021/052376
Kind Code:
A1
Abstract:
The embodiments of the present application relate to the field of digital signal processing. Disclosed are a digital pre-distortion method for a multi-band signal, and an electronic device and a readable storage medium. In the present application, the digital pre-distortion method for a multi-band signal comprises: determining a possible power amplifier distortion according to the configuration of a signal sent by a cell; selecting a basis function of pre-distortion according to the possible power amplifier distortion; solving, according to a pre-collected reference multi-band signal and a corresponding feedback signal, the selected basis function to obtain a pre-distortion parameter; and generating a pre-distortion signal according to the selected basis function and a multi-band signal input during the processing of the pre-distortion parameter.
