传统的信号理论,是建立在Fourier分析基础上的,而Fourier变换作为一种全局性的变化,其有一定的局限性。在实际应用中人们开始对Fourier变换进行各种改进,小波分析由此产生了。小波分析是一种新兴的数学分支,它是泛函数、Fourier分析、调和分析、数值分析的最完美的结晶;在应用领域,特别是在信号处理、图像处理、语音处理以及众多非线性科学领域,它被认为是继Fourier分析之后的又一有效的时频分析方法。 小波变换与Fourier变换相比,是一个时间和频域的局域变换因而能有效地从信号中提

小波分析是建立在泛函分析、调和分析、数值分析、逼近论和傅里叶分析等的基础上发展起来的新的时频分析方法。与经典的傅里叶分析相比较,小波变换是空间(时间)和频率的局部变换,因而能有效地从信号中提取信息,因此小波分析有着许多显著的优点。小波变换是空间(时间)和频率的局部变换,因而能有效地从信号中提取信息。通过伸缩和平移等运算功能可对函数或信号进行多尺度的细化分析,解决了Fourier变换不能解决的许多困难问题。
小波分析是时间—尺度分析和多分辨分析的一种新技术,它在信号分析、语音合成、图像识别、计
