Title:
SIGNAL PROCESSING METHOD AND SIGNAL PROCESSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/199114
Kind Code:
A1
Abstract:
Provided in the present application are a signal processing method and a signal processing apparatus. The method comprises: generating a first digital signal, the first digital signal being a random wideband signal; a DAC sampling the first digital signal at a first sampling rate, so as to obtain a first analog signal; obtaining a second digital signal, wherein the second digital signal is obtained by means of performing first processing on a third digital signal, the first processing comprises resampling, the third digital signal is obtained by means of an ADC sampling the first analog signal at a second sampling rate, the second sampling rate is different from the first sampling rate, and the sampling rate of the second digital signal is equal to the first sampling rate; and calibrating the interleaved distortion of the DAC according to the first digital signal and the second digital signal. According to the present application, the interleaved distortion of a DAC may be effectively calibrated.
