I am working on a research paper regarding EEG signal preprocessing. The first stage includes denoising the signal. However, since I need to evaluate the performance of the method I am using, I thought of
- Using a noise free signal
- Add white Gaussian noise to it
- Denoise it
- Compare the denoised signal with the original one.
Is there a data base that contains real recordings of EEG signal ( not simulated ) and without any additive Gaussian noise. If not, is there any other way that I can use to evaluate my denoising method?
