Secondly , wavelet transform is applied to compute the arrival time of the lamb wave group velocity experiments results demonstrate that wavelet transform can improve the precision of damage localization
其次，本文采用小波分析方法提取lamb波群速度的到达时间，获得了比阈值法及互相关方法更高的精度。
The matching pursuit techniques are applied to enhance speech signal , and a method to determine the threshold of coherent ratio is provided in the enhancement procedure based on matching pursuit . with the method , the noisy signal can be efficiently enhanced in a rather wide range while the statistical property of signal and noise is unknown
运用匹配跟踪技术处理了语音信号增强问题，给出了匹配跟踪信号增强过程中相干比阈值的确定方法，实现了在未知信号与噪声统计特性的情况下，在相当大的范围内明显增强信号的目的。
