摘要
介绍了瞬态信号波至点检测主要的方法:利用self-adaptation cancellation自适应对消原理的自适应权向量法(AWVM)、基于时频分析的Gabor变换法和利用小波分析的多尺度小波分解法以及单尺度小波变换法,并列出了其中关键的公式,使得它们自成整体;最后还分析它们的优缺点,并改进了检测函数。提出可供研究的方向。
The main method of transient signal arriving points detection is introduced, which includes the adaptive weight vector method (AWVM) lying on adaptive canceling theory,the Gabor transform method based on temporal frequency analysis, the MRA method and wavelet transform method on one dimension. The latter two both rely on the theory of wavelet analysis. The list of the pivotal formulas of each method brings themselves into a whole. At the same time, the relative merits are cladfled in this paper.
