Title:
ELECTRONIC DEVICE FOR PROCESSING INPUT SIGNAL OF POWER AMPLIFIER AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/085780
Kind Code:
A1
Abstract:
Provided is a method of processing an input signal of a power amplifier in an electronic device. A digital predistortion device is obtained which digitally predistorts an input signal of the power amplifier by using a neural network model previously trained to digitally predistort an input signal of the power amplifier on the basis of signals inputted and outputted to and from the power amplifier, obtained as the power amplifier operates in a plurality of different environments, and a plurality of environment-related information items, each corresponding to a different environment. In the method, an input signal with respect to the power amplifier is obtained; information concerning the environment of the power amplifier is obtained; on the basis of the obtained environment information, the input signal is digitally predistorted using the digital predistortion device, such that an output signal with respect to the input signal processed by the power amplifier is not distorted; and the digitally predistorted input signal is inputted to the power amplifier.
