Signal Reconstruction from Modulus Maxima of Signal's Wavelet Transform
Shan Chen · Journal of Chongqing University of Posts and Telecommunications · 2000
Based on the multiscale idea,it is pointed out that wavelet transform modulus maxima(WTMM) detect the singularity of signals.The signal can be reconstructed from the WTMM.After that,an algorithm is developed that removes the WTMM related to noise from signals by the threshold selection method and improves the qualities of reconstructing signals.
