- DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具,直接计算DFT的计算量与变换区间长度N的平方成正比。当N较大时,因计算量太大,直接用DFT算法进行谱分析和信号的实时处理是不切实际的。快速傅立叶变换(Fast Fourier Transformation,简称FFT)使DFT运算效率提高1~2个数量级。其原因是当N较大时,对DFT进行了基4和基2分解运算。FFT算法除了必需的数据存储器ram和旋转因子rom外,仍

WAVE-weifengyin
- 小波变换具有多分辨率分析的特点,并且在时频两域都具有表征信号局部特征的能力。小波变换通过将时间系列分解到时间频率域内,从而得出时间系列的显著的波动模式,即周期变化动态,以及周期变化动态的时间格局(Torrence and Compo, 1998)。小波(Wavelet),即小区域的波,是一种特殊的、长度有限,平均值为零的波形。它有两个特点:一是“小”,二是具有正负交替的“波动性”,即直流分量为零。小波分析是时间(空间)频率的局部化分析,它通过伸缩平移运算对信号(函数)逐步进行多尺度细化,能自动适
