Abstract

The invention provides a signal processing method and a mobile terminal. The method comprises the following steps: obtaining an input signal: performing predistortion processing and power amplification processing on the input signal in sequence to obtain a to-be-sent signal that is sent to a base station; performing difference analysis on the input signal and the to-be-sent signal to obtain an analysis result, and reporting the analysis result to a cloud server; and receiving a pre-distortion parameter sent by the cloud server according to the analysis result, and storing a corresponding relationship between target waveform information and the received predistortion parameter, wherein the target waveform information is the waveform information of the input signal. By adoption of the signalprocessing method provided by the embodiment of the invention, the problem that the signal predistortion scheme of the current mobile terminal is difficult to cope with the diverse waveform signalsin a 5G network can be solved.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a signal processing method and a mobile terminal. Background technique [0002] At present, the main process for a mobile terminal to send a signal to a base station is to generate a first signal inside the mobile terminal, and send the first signal to an internal power amplifier (PA, power amplifier), and the power amplifier amplifies the first signal, and the mobile terminal Send the amplified signal to the base station. When the PA amplifies the signal, the signal will be distorted due to the non-linearity of the PA. Therefore, a DPD (Digital Pre-Distortional, digital pre-distortion) processor is usually installed in the mobile terminal, and the DPD processor is used to process the first signal first. Pre-distortion processing, and then the pre-distortion processed signal is sent to the base station through the PA, so that the pre-distortion processing is used to impro...
