冈萨雷斯编写的数字图像处理Matlab版，是Matlab和图像处理的最佳组合(A classical digital image processing books, tells the classic algorithm for digital image processing.)

本代码对OFDM中载波频偏对系统误码率的影响进行了全面的仿真和比较，对加深对OFDM载波同步技术的理解很有帮助(The code in OFDM carrier frequency offset the impact of the system bit error rate of a comprehensive simulation and comparison to deepen the understanding of OFDM carrier synchronization helpful)

这是简易的BPSK信号调制，把文件放入matlab的文件库中，通过在matlab的命令窗口直接调用功能函数并运行，可以直接看到仿真结果。(This is a simple BPSK signal modulation, the documents placed in a the Matlab file library, call function directly in the Matlab command window and run the simulation results can be seen directly.)

可以利用拉格朗日插值方法解决多项式逼近问题(Lagrange interpolation method can be used to solve the problem of polynomial approximation)

对地震波进行数值模拟，设置不同波速的分界面模拟地震波传播(Seismic wave numerical simulation under different wave velocities)

本程序包括直接序列扩频，跳频扩频和跳频多址的相关程序(This procedure, including direct sequence spread spectrum, frequency-hopping spread-spectrum and frequency hopping multiple access procedures)

电机控制matlab仿真模型，来源于某驱动公式，有一些库文件没有，但还是有很高的参考价值的(Matlab simulation model of motor control, from a formula-driven, there are no library files, but there is still a very high reference value)

说明：  数字信号处理设计与仿真分析 (1)建立两个模拟信号的数学模型 sa1(t)和 sa2(t)， 其中 sa1(t)是有用信号， sa2(t)是干 扰信号。 两个信号的中心频率、信号带宽等参数由学生自己选定，要求两个信号的频谱不重 叠， sa2(t)的幅度比 sa1(t)的幅度高 20dB， 两个信号时域叠加得到合成信号 xa(t)， 即 xa(t)= sa1(t)+ sa2(t) 设计计算机程序仿真产生 sa1(t)、 sa2(t)、 xa(t)信号， 分别画出三个模拟信号的时域波 形和频谱图；(Establish two mathematical models of analog signals sa1(t) and SA2 (t), where SA1 (t) is the useful signal and SA2 (t) is the dry signal Interference signals.)
