this file try to simulat defualt data in matlab this data is collect from inertial measuring unit

多组处理，仅展开一个区块的折叠效果(原生Js和jQuery版)，俗称“手风琴菜单”，习惯叫做折叠菜单，一个页面中布置了多组菜单，部分代码释义如下： 　　var navItem=iBase.Id(‘demo‘).getElementsByTagName(‘h2‘) //此处将jQ区块中的h2也取到了,所以页面会有个小小的错误 (Multiple sets of treatment, only one block to start folding effect (native Js and jQuery version), commonly known as accordion menus , used to be called folding menu, a page layout of the multiple sets of menus, the interpretation of the code is as follows: var navItem = iBase.Id ( demo ) getElementsByTagName ( h2 ) . // Here jQ block will also take to the h2, so the page will have a small mistake)

用KNN仿真WiFi室内定位，指纹法室内定位(KNN simulation using WiFi indoor positioning)

小波包4级分解及特征向量空间的建立，希望对大家有用(4 wavelet packet decomposition and feature vector space for the establishment, in the hope that useful to everybody)

自己写的卷积编码MATLAB程序，已将验证过了，没问题，可以用的哈！(Wrote it myself, convolutional coding MATLAB program has been verified, and no problem, you can use Ha!)

该压缩包里包括了三个pdf文档，分别对Simulink基本功能模块作了介绍，并将其在matlab中做了一定的实例讲解(The compressed bundle includes three pdf documents, made ​ ​ an introductory basic functional blocks of the Simulink, and a certain amount of examples to explain in matlab)

fdtd program，using the matlab program ，very good

提取原始信号的功率谱就可以看出在哪个频带的能量比较高，噪声主要集中在哪里，这样就可以专门分析那个频带的噪声(The power extracted the spectrum of the original signal can be seen in which frequency band energy is high, the noise is mainly concentrated in where, so that it can be devoted to the analysis of the frequency band of noise)

本程序为通信系统中的GMSK调制程序，对于研究通信调制解调的人来说十分有用！(This procedure for the communications system GMSK modulation process, the study of communication modem very useful for people!)
