| Abstract: | In this paper, the authors present a signal denoising technique by hardthreshold based on redundant discrete wavelet transform inspired by Donoho algorithm. This method can be used to reduce the oscillating effects induced by Donoho algorithm, and the experiment result also indicates that the method is effective. |
