FIR滤波器，实现了消除心电信号中的杂音。(FIR filter, to achieve the elimination of noise ECG.)

matlab中较常用的一些指令，希望对学习matlab的人有帮助(matlab some of the more commonly used commands, in the hope that people learn to help matlab)

说明：  本次设计是对GSM TCH/FS信道进行编码设计及性能仿真,仿真通信系统包括内外编码器、交织重排器、加性/突发和混合干扰信道、去交织反重排器、内外译码器，模拟了信息从信源到信宿的全过程； 在高斯噪声、突发干扰或混合信道及瑞利信道下测试每个步骤对误码率和系统性能的影响，通过数字及图形的比较，得出通信系统中各个模块的作用。另外，在GSM TCH/FS 的基础上建立GSM TCH/EFS 信道，对相应的信道环境进行仿真，得出误码率分析。 (This design is the GSM TCH/FS channel encoded design and performance simulation, simulation communication system, including internal and external encoder, interleaving rearrangement device, the additive/burst and mixed interference channel, to the cutting device against rearrangement, internal and external decoding and analog information from the source to the destination of the whole process in Gaussian noise, sudden disruption or mixing channel and Rayleigh channel to test each step of the bit error rate and system performance, by comparison of digital and graphic obtained communication systems the role of each module. In addition, GSM TCH/FS based on the established GSM TCH/EFS channel, the corresponding channel environment simulation, the error rate analysis)

这里给出了梯度追踪的matlab代码，对于研究信号处理的人员具有一定的帮助作用(Here are the gradient tracking matlab code, for the study of signal processing has some helpful staff)

fpga仿真，关于时钟，所有文件都在里面，可以直接用(fpga，simulate clock，all files in it)

亮度人脸检测算法，能快速识别人脸，精度高，速度快(Brightness of face detection algorithm to quickly identify human faces, high precision, fast)

GLCM feature for image segmentation

说明：  频域的模态参数识别方法之一，可以对振动信号进行分析处理，得出结构的固有频率，阻尼比，振型系数，方法很好，程序完整，(Frequency-domain modal parameter identification methods that can analyze the vibration signal processing, draw the structure of natural frequencies, damping ratio, mode shape coefficient, very good method, program integrity,)

对于给定的数个离散数据点，使用3次NURBS（非均匀有理B样条曲线）进行插值拟合。该算法程序能够反算出NURBS曲线控制点并绘制经过给定离散点的插值曲线。(For a given number of discrete data points, the 3 NURBS (nonuniform rational B spline curve) is used for interpolation fitting. The algorithm can calculate the control point of NURBS curve and draw the interpolation curve of the given discrete point.)
