摘要:Current denoising techniques for signals are mostly conducted in the wavelet transform domain. In this paper, a new denoising approach for denoising the signals in the Framelet domain is proposed. Medical signals are initially decomposed using framelets. After the deco mposition, they are denoised using a new thresholding approach using hard and soft thresholding. The recomposed signal is then obtained and Signal to Noise ratio value is calculated. The results are compared with that obtained by wavelet technique
