直线阵采用切比学夫加权控制主旁瓣比，抑制噪声。此程序基于常规波束形成实现，程序思路清晰，适合刚接触阵列信号处理的人参考。(Linear array by cutting the right of control over the primary school laid upon the side-lobe ratio, noise suppression. This program is based on conventional beamforming implementation process with clear ideas for people new to reference array signal processing.)

三相光伏阵列的仿真，能够完成仿真的内容，可以做到程序(The simulation of the three-phase PV array, able to complete the contents of the simulation, can be done program)

OFDM，QPSK调制下仿真程序，包括信道编解码，调制解调，上下采样(OFDM, QPSK modulation simulation program, including channel coding and decoding, modulation and demodulation, and down sampling)

本例用来说明复时谱在具有回声信号测量中的应用，这是数字信号处理的前沿课题之一。(In this case when used to describe the complex spectra with echo signal measurement, which is the forefront of digital signal processing one of the topics.)

遗传算法相关介绍，内含详细的PPT课件、PDF及用matlab写的源码(Genetic algorithm-related presentations, PPT contains detailed courseware, PDF, and with source code written in matlab)

利用黄金分割法来求解目标函数的局部极小值。(Functions using golden section method for the minimum.)

非线性扩展卡尔曼滤波算法的matlab程序(Description:This is a tutorial on nonlinear extended Kalman filter (EKF). It uses the standard EKF fomulation to achieve nonlinear state estimation. Inside, it uses the complex step Jacobian to linearize the nonlinear dynamic system. The linearized matrices are then used in the Kalman filter calculation. The complex step differentiation seems improving the EKF performance particularly in accuracy such that the optimization and NN training through the EKF are better than through the UKF )

指纹识别源代码。思路完全是按照文件夹中网页里介绍的方法，即提取指纹中的分叉点和端点的位置作为指纹的特征值。由于今天太忙，对图像的预处理作的很失败，程序会提取出很多伪点，而指纹轮廓也没有想出办法过滤。汗，你看看能不能参考把。 三个m文件，fd.m提取指纹中的分叉点，fd2.m提取指纹中的端点，Cpoint.m则是前两个文件运行中需要调用的掩模函数。(fingerprint identification code. Thinking is entirely in accordance with the folder on the website Lane, that the fingerprints of the bifurcation point and endpoint position as a fingerprint eigenvalues. As today are too busy, the image preprocessing for the failure, the program will extract a lot of pseudo-point, and the fingerprint profile nor find a way to filter. Khan, you can look at the information put. 3 m documents, fingerprints fd.m the bifurcation point, fd2.m fingerprints of endpoint, Cpoint.m are two documents before the operation need to call the mask function.)
