This file contains a lab which is developed to implement a low pass filter using windowing technique. We study the way how to design FIR digital filters and how Matlab offers tools for the design.

基于非局部均值图像去噪，对高斯加噪声有很好的去除效果，其中的修改程序，加入了对称处理，处理对称图像效果更好(Based on non-local means image denoising, the high Alaska noise removal, which modify the program, joined the symmetrical treatment, processing symmetrical image effect better)

遗传算法寻优寻优，（调用matlab自带函数）解决一般系统的参数设定问题。(Genetic algorithm optimization optimization (call matlab own functions) to solve the general system parameter setting.)

高阶循环累积量对信号进行识别，该文件代码完整，适合学习，可以直接更改来识别信号(Order cyclic cumulants of the signal recognition, the document code integrity, for learning, you can change to identify the signal directly)

说明：  通过步进电机的数学模型对二相步进电机进行仿真，并通过卡尔曼滤波处理数据，最终通过处理后的数据预估两相步进电机的相电流和相电压。(The mathematical model of the stepping motor is used to simulate the two-phase stepping motor, and the data are processed by Kalman filter. Finally, the phase current and phase voltage of the two-phase stepping motor are predicted by the processed data.)

UWB信道的仿真程序，是一个比较经典和难得的程序！(UWB channel simulation program, is a more classic and rare procedure!)

说明：  基于matlab的数字语音信号的脉冲编码调制源代码。(Matlab-based digital audio pulse code modulation signal source code.)

对于初学者来说，有助于理解滤波器的原理还附有简单的matlab编程(For beginners to understand the principles and simple filter matlab programming)

最优化算法中的带Armijo搜索求步长的拟牛顿算法的源码，matlab编程实现，希望对大家有用。(Optimization algorithm with Armijo search seeking step quasi-Newton algorithm source code, matlab programming, and hope to be useful.)
