说明：  数字pid控制仿真，包括位置式pid算法和增量式算法(figures pid control simulation, including location-pid algorithm and incremental algorithm)

说明：  这是一个MATLAB中文工具箱，提供了很多有用的，MATLAB自身没有的数学建模的源码，例如：数据拟合，微积分和微分方程，随机模拟和统计分析，数学规划，离散优化等，并有中文的注释。非常好！(This is a MATLAB toolbox Chinese, providing a lot of useful, MATLAB does not own the source of mathematical modeling, such as: data fitting, calculus and differential equations, stochastic simulation and statistical analysis, mathematical programming, discrete optimization, Notes and Chinese. Very good!)

ISAR成像 包络对齐采用相关法对齐，相位聚焦采用多普勒中心跟踪法 和秩估计法(ISAR imaging envelope alignment using correlation method align phase focusing using the Doppler centroid tracking method and rank estimation method)

A multiplexing system with NT transmit and NR equals NT receive antennas is designed. The main challenge fo systems lies in the non-orthogonality of the transmission channel. This can be solved by turbo processing. Turbo channel encoder is used for converting the bits in its suitable form. Then different M-ary QAM is compared.

利用自然梯度算法来对于5 类信号进行盲信号分离，采用自然梯度法对混合的信号进行 分离并分析其性能，并比较不同步长对于信号分离的影响(Use of the natural gradient algorithm for the five types of signals blind signal separation, using the natural gradient method for mixed signal Separation and analysis of its performance and compare sync signal separation for the impact of long)

利用matlab编写的获取单应矩阵的源程序，可用于计算机视觉图像配准等程序中。(Get prepared using matlab homography of the source, can be used for computer vision, image registration and other procedures.)

MATLAB下通过多种小波实验了解小波变换的原理教程及示例代码(MATLAB wavelet through a variety of experiments to understand the principle of wavelet transform tutorials and sample code)

生成samples.mat文件的相关源程序。需要一百个wav文件输入。(The relevant source files generated samples.mat. Need a hundred wav file input.)

跳频系统的仿真,适合于初学者，算法还算清晰，还不错，希望对你有用(Simulation frequency hopping systems, suitable for beginners, the algorithm is fairly clear, well, I hope useful to you)
