摘要
简述了小波理论近年来的发展概况,将小波变换与加窗富里叶变换进行系统深入比较,对小波分析在信号检测、控制系统故障诊断及非线性分析中的应用研究进行了综述。
The development about wavelet theory is briefly described and wavelet transform is systematically compared with windowed Fourier transform in this paper. Then, the application of wavelet analysis in signal detection,control system fault diagnosis and nonlinear analysis is synthetically stated ,and some research areas about wavelet transform are pointed out.
