Abstract

Wavelet shrinkage methods have been very successful in denoising of biological signals. A New wavelet shrinkage method for denoising of biological signals is proposed in this paper. This method is applied to denoise ECG signal corrupted with additive Gaussian noise. We compared the performance of this new method with that of popular shrinkage methods based on hard and soft filters. Simulation results showed that this new method is superior to hard and soft shrinkage methods.
