Signal processing method, electronic equipment and storage device

Abstract

The invention discloses a signal processing method, electronic equipment and a storage device. The method comprises the following steps: acquiring at least one first signal acquired by a signal acquisition device; decomposing the first signal into a plurality of first sub-band signals in a frequency domain, wherein the plurality of first sub-band signals have different center frequencies; performing non-target signal elimination on the first sub-band signals to obtain second sub-band signals, wherein at least part of non-target signals are reserved in the second sub-band signals; performing target signal elimination on the second sub-band signals to obtain third sub-band signals; synthesizing the corresponding second sub-band signal and third sub-band signal to obtain fourth sub-band signals; and synthesizing the plurality of fourth sub-band signals to obtain a second signal. According to the scheme, the mutual interference among the plurality of first sub-band signals during signal processing can be reduced, and the enhancement effect on the target signal in the second signal is improved.

Description

technical field [0001] The present application relates to the technical field of signal processing, and in particular to a signal processing method, electronic equipment, and a storage device. Background technique [0002] With the continuous development of smart devices and the wider application of human-computer interaction technology, the accuracy requirements for signal processing are also gradually increasing. When the signal acquisition device collects the signal, there are usually interference signals in the signal, that is, Non-target signals, therefore, the signal needs to be processed to filter out the non-target signals in the signal, and then achieve the effect of enhancing the target signal in the signal. [0003] In the existing signal processing method, short-time Fourier transform is performed on each signal after obtaining multiple signals, and a longer window length cannot be selected in consideration of signal delay when performing short-time Fourier trans...

AI Technical Summary

Problems solved by technology

[0003] In the existing signal processing method, short-time Fourier transform is performed on each signal after obtaining multiple signals, and a longer window length cannot be selected in consideration of signal delay when performing short-time Fourier transform. Therefore, each The spectrum leakage between the frequency bands corresponding to the signal is relatively large, and any subsequent filtering operation will affect the adjacent frequency bands, resulting in the target signal of the adjacent frequency bands being also affected.
