Title:
SIGNAL PROCESSING METHODS AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/165322
Kind Code:
A1
Abstract:
Signal processing methods and a storage medium are disclosed in the present invention. A method comprises: eliminating a local oscillation leakage signal from a first waveform signal to obtain a second waveform signal, the first waveform signal being output by a wave generator; converting the second waveform signal into a third waveform signal in a target signal channel; correcting the third waveform signal on the basis of a frequency mixing signal to obtain a fourth waveform signal; compensating the fourth waveform signal on the basis of difference information between the fourth waveform signal and a target waveform signal of the wave generator, and outputting the compensated fourth waveform signal. The present invention solves the technical problem of low accuracy of waveform signal processing.
