说明：  OFDM在AWGN信道下的仿真，用MATLAB实现，一共有6个程序。(OFDM AWGN under the simulation, using MATLAB, a total of six procedures.)

在matlab环境下，将YUV视频格式转换为matlab可以处理的mov视频格式(In the matlab environment, the YUV video format conversion mov video format that can be processed for matlab)

说明：  经验模态分解(Empirical Mode Decomposition,EMD)法是黄锷(N. E. Huang)在美国国家宇航局与其他人于1998年创造性地提出的一种新型自适应信号时频处理方法，特别适用于非线性非平稳信号的分析处理。(Empirical Mode Decomposition)

加道夫—切比晓夫波束形成,旁瓣高度相等，主瓣和旁瓣比可以设定。(Plus Astoria- cutting beam forming than convincing Love waves sidelobe height equal to the main lobe and sidelobe ratio can be set.)

说明：  《MATLAB在电子信息课程中的应用》中的第五章的习题源程序( MATLAB curriculum in electronic information applications in Chapter V source Exercises)

The WAVELETCHANGE dialog is initiated by calling WAVELETCHANGEINIT which then calls WAVELETCHANGE. With one exception, WAVELETCHANGE is never called directly from another program. Tha exception is when another program has a figure handle that may be a legitimate WAVELETCHANGE window or not. Calling waveletchange( test ,figurehandle) will return 1 if it is a legit change window and zero otherwise.

三种信号进行EMD分解，IMF分量绘图 进行比较显示(Three signals for EMD decomposition, IMF component drawing comparison shows)
