摘　　要：在论述了小波分析、信号奇异性与小波变换模极大值性质关系的基础上 ,本文给出了一种基于小波变换模极大值的信号去噪算法。仿真结果表明了该算法的有效性 ,既能有效的消除噪声 ,又能较好地保留了原始信号的突变信息。Based on the wavelet transform and the relation between signal singularity and wavelet transform modular maximum, a noise removal technique is discussed. The simulation results show this method is effective, and it can remove noise from signal effectively and keep abrupt change in signal.
