Hello,
I have a question regarding a signal denoising with wavelets. I was able to successfully denoise signals using the method described in Chapter 13.
However I have a problem when I try to apply the same technique on a moving (non-stationary) signal. I have no idea how to treat the discontinuity between say the signal from 0 to 512 points and a signal from 512 to 1024 points. I've tried to add the new data points to the old signal basically doing a new denoise for 0 to 1024 but I still have a discontinuity between the two data sets. The problem is that I want to implement this denoising procedure in a real time system, and I don't want to change the past when I add a new set of data to my initial data buffer.
Any help will be appreciated,
Thanks,
Do
