Title:
DIGITAL PRE-DISTORTION PROCESSING METHOD AND DEVICE, COMPUTER APPARATUS, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/052459
Kind Code:
A1
Abstract:
The present invention relates to a digital pre-distortion processing method and device, a computer apparatus, and a readable storage medium. The method comprises: acquiring a wideband IQ signal; determining, according to a forward channel signal and a feedback channel signal corresponding to the wideband IQ signal, a pre-distortion coefficient for digital pre-distortion processing; and acquiring a normal channel signal, performing, according to the pre-distortion coefficient, digital pre-distortion processing on the normal channel signal, and performing power amplification on the normal channel signal after digital pre-distortion processing. The present invention solves the problem in which a digital pre-distortion function is unable to be performed on a signal for a narrow carrier bandwidth, and enables the digital pre-distortion function to be applied to a communication system with a narrow carrier bandwidth.
