语音混合编码melp（混合激励线性预测）算法的matlab实现(use matlab to implement melp)

是由斯坦福大学的Andrea Goldsmith编著的关于无线通信的教材，很经典.(This book is writen by Andrea Goldsmith who is from Stanford University. It is a classic book for wireless communication.)

直扩系统中的多径干扰信号的估计消除技术，通过仿真标量多径对直达信号的鉴相特性的影响。。(DSSS system multipath interference estimate signal cancellation technology, through the simulation of scalar multi-path of the direct signal phase characteristics. .)

该函数实现的是激光光斑中心检测。首先对光斑进行预处理，然后利用灰度重心法来计算得到光斑的中心坐标,最后利用MATLAB的绘图功能描绘出光斑中心位置的变化情况。(This function is implemented in the laser spot detection. First spot pretreatment, and then use the barycenter method to calculate the coordinates of the center of the spot, the final use of MATLAB graphics depict the changes in the spot center position.)

余数定理用于多基线相位干涉仪的解模糊中要求基线关系互质(Remainder theorem for the solution of multi-baseline interferometer fuzzy requirements baseline relations coprime)

数字信号处理中光于数字滤波器的仿真，用到了周期图法，能得到相关信号的功率谱。(Digital signal processing is the simulation of digital filter.)

说明：  TVP-VAR模型matlab代码,新手小白可参考，自学入门必备，代码来源Nakajima文章。(TVP-VAR model matlab code, novice little white can refer to, self learning entry necessary, code source Nakajima article.)

包括数据分析、绘图等等,DC-DC部分采用定功率单环控制，用MATLAB实现动态聚类或迭代自组织数据分析，用于图像处理的独立分量分析，一些自适应信号处理的算法，构成不同频率的调制信号。
