You can use the wdenoise function:

https://www.mathworks.com/help/wavelet/ref/wdenoise.html

Yassine Tounsi

Have you used wavemenu of matlab ?

type

>> wavemenu

a graphical interface appears, it contains 1 and 2 dimentsional wavelets with differents wavelets mothers and scales. You upload your signal and you can denoise your data easily.

Good luck

Akram Elhelbawy

thank you all ... I need something to work online.

Reeta Devi

For 1D signals, use wden function in MATLAB.

Reeta Devi is there a way to do it online ?

I mean to denoise but while I am running the simulation?

Devi Rajendran

wpt function can be used to find wavelet packet transform.

Yahya T Qassim

You can do your own Matlab code by analysing the 1D signal with the DWT into 3 levels at least then apply a soft or hard threshold on the details part of the WT, then reconstruct the original signal using the mirror wavelet filter.
