face recognition through matlab

利用MATLAB实现正交滤波器组的设计。(Use MATLAB to achieve the design of orthogonal filter banks.)

MFCC参数和LPCC参数需要频繁使用的语音的说话人识别分析还需要使用大量的这些特征参数,这就需要研究MFCC和LPCC算法和参数提取的原则。因为我们需要了解与人交谈的过程中,我们要进行建模 率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(MFCC parameters and LPCC parameters are parameters of speaker recognition which requires frequent use of voice analysis also need to use a lot of these characteristic parameters, This requires research MFCC and LPCC algorithm and the principle of parameter extraction. Because we need to understand the process of talking to people, we want to conduct a speaker modeling the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula)

说明：  用MatlaB编程实现GMSK在移动通信系统中的调制解调(Programming with MatlaB GMSK mobile communication system in the modulation and demodulation)

这个程序是王永良的空间普估计理论与算法中的幅相误差校正中自校正算法，找了好久找不到源程序，此程序是本人亲自编写，此方法的缺点是容易陷入局部最优解，具体看程序仿真图(This program is estimated Pu Wang Yongliang space theory and algorithms of amplitude and phase error correction in self-calibration algorithm, for a long time could not find the source, this program is a personally written, the disadvantage of this method is easy to fall into local optimal solution, specifically to see the program simulation map)

实现用MATLAB程序产生歌曲，包括卡农，小星星和加勒比海盗的代码。(Songs MATLAB program, including Canon, little star, and Pirates of the Caribbean code.)

说明：  optisystem和MATLAB联合仿真(Joint simulation of optisystem and MATLAB)
