基于小波变换的信号重构

Signal reconstruction based on wavelet transform

在信号分析中，奇异点和不规则性经常携带有重要的信息．文中利用小波变换模极大值对应的点来提取奇异点，并讨论了如何运用凸集上投影的方法来重构原始信号．

Singularites and irregular structures often represent the most important information for signal analysis. This paper presents an iterative algorithm for signal recovery from discrete time wavelet transform modulus maxima. This signal recovery algorithm is developed by using the method of projections onto convex sets.
