从MatlabSimulink模型到代码实现(阿斯利康；jdjgaslkg)

这个是我个人编写的短时傅里叶变换的函数matlab.适用于语音压缩与语音分析.在其中可以加入一些自己的代码，即可改成phase vocoder(this is the STFT function which is wrote by myself(matlab). It is suit for speech compression and analyse. if you add some code in it, it can turn to a phase vocoder straightforward. )

能量谱分析计算,小波包分析提取振动信号中的特征频率，关于神经网络控制。( Energy spectrum analysis and calculation, Wavelet packet analysis to extract vibration signal characteristic frequency, On neural network control.)

％％目标在监控区内运动轨迹为佯攻机动曲线时的定位( Target in the surveillance zone trajectory curve for the feint at the time of mobile positioning)

3条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真，并与理想信道(没有多径)作比较。 需要的支撑子程序为qpsk_berest.m,vxcorr.m,random_binary.m.(Three fixed-path multipath AWGN channel QPSK system BER performance simulation, and with the ideal channel (no multipath) for comparison. Need the support of subprogram for qpsk_berest.m, vxcorr.m, random_binary.m.)

提取信号七个基于瞬时信息的特征：零中心归一化瞬时幅度功率谱密度的最大值,零中心归一化瞬时幅度绝对值的标准偏差，零中心非弱信号段瞬时相位非线性分量绝对值标准偏差，零中心非弱信号段瞬时相位非线性分量标准偏差，零中心归一化的非弱信号段瞬时频率绝对值的标准偏差，一个信号段的归一化瞬时频率功率谱密度的最大值，根据信号 QPSK 和16QAM在 XI 轴投影的不同表现，提出特征参数。(extract information based on the instan eous features : In the center is one of the instantaneous rate of the power spectral density of the maximum, is a center to the absolute value of the instantaneous rate of the standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component absolute standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component standard deviation, In the center is one of the non-weak signal of the absolute value of the instantaneous frequency standard deviation, a signal to one of the instantaneous frequency of the power spectral density of the maximum, According to 16QAM and QPSK signals XI axis projection in the different performance parameters raised.)

用Matlab实现一副图片中多个人脸的识别，另附有一片文章以帮助了解，识别效果非常好，适应性很强。(Using matlab to achieve multiple faces recognition in a picture,and attach a text to help understand, the effect is very good,strong adaptability.)

OFDM系统中的峰均比问题的Matlab仿真(PAPR OFDM system Matlab simulation of the problem)

matlab经典教材并且其中有部分确实写得不错(Matlab classic textbook and some really well-written)
