| 摘 要： | 讨论了连续复小波变换在瞬态信号波至点检测中的运用,提出了一种新的信号波至点检测函数.这种检测函数运用了能量归一化的方法,它不仅能够保证信号波至点的有效检测,而且还拓宽了小波变换中用于信号检测的尺度范围.仿真实验证明,这种检测函数是有效的.

| Abstract: | A new measure function using in the detection of arriving points is presented. It is based on the advantage of complex-valued CWT in the detection of transient signal's arriving points and the energy-unify theory. It can not only guarantee the detection of the arriving points but also enlarge the CWT's scale range. The experiment results show that it is an effective tool in the detection of arriving point. |
