说明：  HHT主要内容包含两部分，第一部分为经验模态分解（Empirical Mode Decomposition，简称EMD），它是由Huang提出的；第二部分为Hilbert谱分析（Hilbert Spectrum Analysis，简称HSA）。简单说来，HHT处理非平稳信号的基本过程是：首先利用EMD方法将给定的信号分解为若干固有模态函数（以Intrinsic Mode Function或IMF表示，也称作本征模态函数），这些IMF是满足一定条件的分量；然后，对每一个IMF进行Hilbert变换，得到相应的Hilbert谱，即将每个IMF表示在联合的时频域中；最后，汇总所有IMF的Hilbert谱就会得到原始信号的Hilbert谱。(The main content of HHT includes two parts. The first part is Empirical Mode Decomposition (EMD), which was proposed by Huang, and the second part is Hilbert Spectrum Analysis (HSA). Simply speaking, the basic process of HHT processing non-stationary signals is: firstly, the given signal is decomposed into several intrinsic mode functions (represented by Intrinsic Mode Function or IMF, also known as intrinsic mode functions), which are components satisfying certain conditions; secondly, Hilbert transform is applied to each IMF. The corresponding Hilbert spectrum is obtained, that is, each IMF is represented in the joint time-frequency domain; finally, the Hilbert spectrum of the original signal is obtained by summing up the Hilbert spectrum of all IMFs.)

VC++毕业设计：简单Ftp客户端的实现源码+设计文档，只是一个简单的FTP上传功能，文档包括了Ftp客户端的各个子模块主要函数功能分析及流程图、FTP客户端文件的显示查询实现、Ftp客户端的各个子模块设计过程及代码分析、7．整个设计过程中遇到的主要问题等，是学习VC++网络编程的好范例。 　　通过这个毕业设计实战，你可以和作者一起了解WinInet API编程的基本知识，熟悉了MFC编程中的一些控件知识，在实战FTP客户端过程中从各方面查找资料来丰富自己的知识的能力。

说明：  OAM经过湍流之后，能量谱扩散，模态不纯，随机相位屏部分自己写，给了mat文件(After turbulence, the energy spectrum of OAM diffuses and the mode is impure)
