本书讲的是Matlab 在电信工程中的应用，包括基础篇、数字信号处理、和神经网络三大部分(Book is about Matlab applications in telecommunications engineering, including basic articles, digital signal processing, and neural network of three parts)

基于Harris原理的亚像素角点坐标检测Matlab程序；直接运行click_calib .m文件即可获得亚像素级角点坐标，附录Ⅱ中的其它函数文件均会被click_calib .m文件调用。(Based on the principle of subpixel Harris corner coordinates detection Matlab procedures run directly click_calib. M file to obtain sub-pixel corner coordinates, Appendix Ⅱ other functions in the file will be click_calib. M file called.)

matlab教材中经典的语音增强算法，voice enhancement 先读入语音文件，然后计算前后信噪比，最后画出波形。(The classic textbook matlab speech enhancement algorithms, voice enhancement before reading the speech file, and then calculate the signal to noise ratio before and after the final draw waveforms. )

对拍摄到得全息图进行重构的程序。缺点，在MATLAB中使用的是近似算法，实际上可以在程序外建立C程序来实现循环从而让结果更精确。(Wavefront reconstruction of digital hologram.)

合成孔径雷达SaR仿真--RD,CS(SaR synthetic aperture radar simulation-- RD, CS )

fir滤波器，7、8、13、14，对信号进行alpha、betagamma滤波，调用方法 Hd = fir_alpha 滤波后信号 = filter(Hd,原信号) 得到的信号是时域信号，plot直接显示(Fir filter, 7, 8, 13, 14, alpha filter for signal method is called Hd = fir_alpha After filtering signal = filter (Hd, the original signal) Signal is time domain signals, the plot showed directly)

Resources for Energy Efficient Mobile Sensing Research (conducted by Yi Wang)

该程序实现了线性kalman滤波进行单目标跟踪，注释详细，并包含了例程(The program implements a linear kalman filter for target tracking, notes in detail and includes routines)

说明：  最优化作业写的小程序 ，BFGS做优化问题的。(BFGS does the optimization problem.)

说明：  一个很好的求信号包络的MATLAB工具包.(A good demand signal envelope of MATLAB tool kit)
