优点：1.对于信噪比高的信号滤波效果好； ％ 2.对于边沿的保护强过阈值滤波，不会产生阈值滤波情况下的过于平滑与Gibbs现象。 ％缺点：1.由于对边沿信号没做任何处理，所以边沿可能会有脉冲噪声保留下来； ％ 2.计算相关系数中，如果计算出来的小波系数点位置偏差大，则相关系数计算受影响； ％ 3.需要迭代运算，迭代的噪声能量阈值选取很重要，这里以开始段无信号处估计噪声； ％ 4.需要迭代运算，所以运算量比阈值法大； ％ 5.受分解层次影响，在大尺度上小波系数点位置偏差更大，相关系数计算不准确。 ％需要具体调整的地方：1.分解的尺度；()

通信原理的MATLAB编程，满足对课本基础知识的理解，包括调制解调。(Communication Theory of the MATLAB programming to meet the basic knowledge to understand the textbook, including the modem.)

说明：  标准label propagation的一个实现版本，实现为函数，可以直接调用即可。(As a standard implementation of label propagation algorihtm, you could integrate into your work freely.)

《matlab在数学建模中的应用》卓金武版，从数学建模的角度介绍matlab的应用。书中内容完全是根据数学建模竞赛的需要而编排的，涵盖了绝大部分数学建模问题的matlab求解方法。源码为《Maltab在数学建模中的应用》的源程序和数据。 ("Matlab in mathematical modeling, " Zhuo Jinwu version, from the mathematical modeling point of view on the application of matlab. The book content is based entirely on the needs of mathematical modeling contest arranged, covering the majority of matlab mathematical modeling method for solving the problem. Source for the "Maltab in mathematical modeling, "the source code and data. )

本程序主要通过EMD和hilbert求IMF，作出HHT归一化能量谱图（三维图），边际谱图和瞬时能量图，并做完备性验证(The program primarily through EMD and hilbert seek IMF, to HHT normalized energy spectrum (three-dimensional map), the marginal spectrum and the instantaneous energy map, and do a complete validation)

粒子群算法的具体代码，简单易行非常好用，放在word中，复制出来可直接使用(PSO algorithm specific code is very simple to use, on the word, copy it can be used directly)
