内有两个MATLAB程序，主要用于语音增强：一个用于向纯净语音文件(wav)添加高斯白噪声，信噪比可选；另一个文件用于测量语音信噪比，对语音增强效果判断(MATLAB, there are two procedures, mainly used for speech enhancement: one for the pure audio files (wav) add white Gaussian noise, SNR optional another document used to measure the voice signal to noise ratio, the effect of speech enhancement judge)

这个程序用于提取信号的包络，用以求取信号的轮廓得到信号的主要信息(This procedure is used to extract the signal envelope, to obtain the main information of the signal to strike a signal contour)

对于一组数据求数据频率。绘制频率分布曲线。matlab求频率函数(Statistics_Toolbox of matlab to draw frequency curve)

线性系统的扰动观测器模型仿真和画图程序，m文件(Simulation of M model for disturbance observer of linear systems)

双基（机载）合成孔径雷达测高——比较没技术含量，因为用的方法是斜距差，没用相位差（还没研究出来），所以误差有点大。(Double-base (Airborne) synthetic aperture radar altimeter- not the technical content of comparison, because the methodology used is inclined away from the poor, no phase difference (not finding out), so a bit big error.)

利用蚁群算法整定PID参数,得到PID的参数，使得系统的动态性能最好(get PID parameters by ACA)

说明：  GMSK 信号在衰落信道中的频偏盲估计,学习阶段，大家共同进步(GMSK signal at the frequency of fading channel偏盲estimates, study phase, the common progress of U.S.)

说明：  实现了免疫算法求解约束优化问题的实例。实验表明，算法具有良好的性能。(The method is the implementation of Immune Algorithm(GA). The experiment results show that the efficiency of the algorithm is better.)

这是支持在MATLAB中进行四元数（哈密顿数）的工具箱，函数丰富，能大大简化四元数运算的速度(This is supported in MATLAB quaternions (Hamilton number) of the toolbox, function rich, can greatly simplify the quaternion computing speed)
