平台（Matlab2008a，Simulink，Sysgen 10.1.03）硬件实现RGB2YCbCr (Platform (Matlab2008a, Simulink, Sysgen 10.1.03) hardware realise of RGB2YCbCr)

说明：  无线通信第三章第十一题的答案Jakes Model 锐利衰落信道(Chapter XI of the wireless communications answer to sharp fading Jakes Model)

用信道编码构造压缩感知测量矩阵.pdf,一篇非常好的论文(Channel coding structure with compressed sensing measurement matrix. Pdf)

本代码实现了人工鱼群算法（ASFA.m）,并用该算法寻找Sphere函数的极小值(This is a ASFA .)

用于立体图像处理过程中两张视差图按照像素规则合图。(For composing two pictures.)

分别实现由MVDR和RLS实现了单波束形成（signal beamfroming using MVDR and RLS）(Were implemented by MVDR and RLS achieve a single beam forming (signal beamfroming using MVDR and RLS))

这是huang的eemd程序，将白噪声加入到了经验模态分解当中，一定程度上抑制了模态混合。(This is huang s emd program, the white noise is added to the empirical mode decomposition which suppress modal mix to some extent.)

设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。 对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。 (Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file. The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)
