Matlab讲义高级第3章，大家分享一下(Matlab senior notes in Chapter 3, we share)

design and implementation of feedforward neural network with BP training algorithm.(include the GUI)

加性白噪声的计算机实现，我们学校老师自己编的实验指导(Additive white noise machine to achieve the guidance of our school teachers have compiled experimental)

说明：  pso优化的支持向量机的时序序列预测 内中有数据 需安装工具箱(Pso-optimized support vector machine needs toolbox to install data in time series prediction)

实现了灰色理论在关联度识别方法在matlab中的应用(Grey achieved recognition in the correlation of in matlab)

This text deals exclusively with signal processing of digital data, although Chapter 1 briefly describes analog processes commonly found in medical devices. This text should be of interest to a broad spectrum of engineers, but it is written specifically for biomedical engineers (also known as bioengineers). Although the applications are different, the signal processing methodology used by biomedical engineers is identical to that used by other engineers such electrical and communications engineers. The major difference for biomedical engineers is in the level of understanding required for appropriate use of this technology. An electrical engineer may be required to expand or modify signal processing tools, while for biomedical engineers, signal processing techniques are tools to be used.

直接扩频捕获Xfast算法仿真(包含可调SNR信息码产生)(dsss acquisition(XFAST))

代码是matlab编写，有例图，可直接运行（注意修改路径）。主要用来检测桥面、路面裂纹，有详细函数功能说明和算法思想，实现了路面规则条纹背景的频率估计，采用频域滤波可有效去除路面图像接近估计频率的噪声，保留目标裂纹，实现了初步的检测功能，但是功能还不完善，可作Demo供大家参考。有兴趣的朋友可以逐步完善、移植，有兴趣的朋友请与我联系。(Matlab code is written, there is case diagram, can be run directly (Note to modify the path). Mainly used to detect bridge, road cracks, a detailed description and algorithms Function thinking to achieve a frequency of road rules striped background estimation, using frequency domain filtering can effectively remove the image close to estimate the frequency of road noise, keep cracking goal to achieve a preliminary detection function, but the function is not perfect, can be used for Demo for your reference. Interested friends can gradually improve, transplant, friends who are interested, please contact me.)

support vector machine （支持向量机）方法是目前分类方法中比较好的一个分类方法，实验证明准确度非常高！(support vector machine (support vector machine) method is a better classification of a classification method, experimental proof of a very high accuracy!)
