emd分解中采用多项式拟合算法消除边界效应(emd decomposition of polynomial fitting algorithm is used to eliminate the boundary effect)

该程序是利用MATLAB来进行遗传算法和BP算法结合的好例子，可以为作参考(that the procedure was carried out using MATLAB genetic algorithm and BP algorithm combines a good example, we will be able to make reference to)

Dv-hop算法的原始算法的源程序，可以了解到原始算法的误差值(Dv-hop algorithm, the original algorithm of the source, I can understand the error of the original algorithm)

本工程实现了将三路合成的DSB信号用椭圆滤波器（低通，带通，高通）滤出； 其中的freqz函数，filter函数，fft函数都自己实现。 每种滤波器都分别用专门的函数分别写出，可以模块化。( This project will be three-way synthetic a DSB signal elliptic filter (low pass, band-pass, high pass) filter out Freqz function of which, the filter function, fft function. Each filter are, respectively, with a special function, respectively, to write, can be modular.)

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)
