A New Wavelet Packet Based Method for Denoising of Biological Signals
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 10
Abstract
Wavelet packets have been found to be effective in denoising of biological signals. Wavelet based denoising methods widely employ hard and soft thresholding filters for denoising the signals. This paper introduces a New thresholding filter for the purpose of thresholding in denoisng of EEG signals using wavelet packets. The functioning of the filter is examined and compared with that of hard and soft filters by applying this filter in denoising of EEG signals corrupted with white Gaussian noise. From the results, it is found that the New filter works better than hard and soft filters in addition to contain their features.
