信号奇异特性的检测及其应用
On Character Detection of a Signal and Its Application
【摘要】 研究了信号发生剧变或有发生剧变趋向的特征 (即信号的奇异特性 ) ,采用一种特殊的积分小波变换可将信号发生奇异特性的位置 (或时间 )确定下来 .并介绍了实验的情况 .
【Abstract】 Sharp changes or change tendency characters of a signal, which are singularities of the signal, are studied in this paper. Moreover, a special integral wavelet transform is used for determining the locations of the singularities of the signal. Two numerical experiments are presented to illustrate the effectiveness of the method.
