| 摘 要： | 本文首先介绍了子波变换的局部时频分析法。基于子波变换系数模极大值同信号奇异性之间的关系，给出了一种利用该极大值信息的信号重建方法。由模拟结果可以看出，这种重建方法的精度在－３５ｄＢ以上。

| Abstract: | The local time-frequency analysis way of wavelet transform is first introduced.Based on the relation between signal singularity and wavelet transform modulus maxima, areconstruction algorithm from this modulus maxima is proposed. Simulation result shows this signalreconstruction has a good approximation and the accuracy is greater than-35dB. |
