| 摘 要： | 本文介绍了一种采用由紧支撑小波的自相关函数所构成的多精度表示来进行瞬时信号的检测方法。这种多精度表示是由紧支撑小波的自相关函数经过伸缩．平移构成，它的基函数是完全对称的，因此具有移不变特性。我们所做的数值模拟实验表明，这种方法为瞬时信号的检测提供了一条实用而有效的途径。

| Abstract: | We apply a multiresolution representation of signals using dilations and transla-tions of the auto-xcorrelation functions of compactly supported wavelets in deteption of transientsignals. Thls representfltion has the properties of shift-invariance and symmetric shape of basefunction. Our numerical experiments show that this is a practicnt and effectual method for de-tection of transient signals. |
