为了克服傅氏变换不能同时保留信号的时间 信息和频率信息的缺点,人们引进了局域波法，它是最近发展起来的处理非线性、非平稳信号的时频分析方法,通过对信号局部特征出发,直接由信号本身构造基函数,具有良好的局部适应性-In order to overcome the Fourier transform of the shortcomings of the time and frequency information of the signal can not be reserved, the int

短时傅里叶变换，用于求解非线性薛定谔方程-Short-time Fourier transform, is used for solving the nonlinear schrodinger equation

仿真效果非常好，时间序列数据分析中的梅林变换工具，关于非线性离散系统辨识。- Simulation of the effect is very good, Time series data analysis Mellin transform tool, Nonlinear discrete system identification.
