| 摘 要： | 鉴于传统信号处理对非平稳信号的局限,小波分析作为一种具备时间-频率局部特性的信号处理方法,已成为众多领域的研究热点.笔者介绍了小波变换的部分性质,分析了小波变换与Fourier变换下的奇异信号特性,并以此进行奇异信号检测. |
| 关 键 词： | 小波变换 奇异信号 Fourier变换 检测 |

| Abstract: | In view of the limitation of classical signal processing method in case of nonstationary.Wavelets is a developing subject,it provides a new local property of the signal in time frequency for the digital signal processing in engineering.In this paper,partial characteristics of wavelet transform were introduced;the characteristics of singular signal were analyzed by the wavelet and Fourier transforms and utilized as characteristics in detecting singular signal and its singularity. |
| Keywords: | wavelet transform singularity signal Fourier transform detecting |
