如意用户网络验证系统1.3

说明：  初学随机过程在MATLAB仿真上会有不懂，关于谱密度的几个例题(Some examples about spectral density are not clear in MATLAB simulation of initial stochastic process.)

硬件控制程序，简单 仅供参考-hardware control procedures, simple is for reference only

C++练习小代码，适合新手。 集合了10个新手练习C++的代码，比较简单，主要是给刚开始学习C++的童鞋一些入门小代码，如果是老手就不用下载了。

快捷一键下单程序，通过键盘一个字母就可以完成下单(Quick click a single program, through the keyboard a letter can complete the order)

c程序非常使用的，简单的程序！直接复制就可以运行的！对二级考试很有用！(c program is very to use, simple procedure! Replication can be run directly! Examination is useful for two!)

说明：  对碰撞信号特征进行降维和聚类分析，提高分类精度(Reducing dimension and clustering analysis of collision signal features to improve classification accuracy)

利于MATLAB实现OFDM的发送和接收，具体过程发送端先通过QPSK调制，之后进行IFFT变换，然后再添加循环前缀，接收端是一个逆过程。该程序还有另外一个的功能是信道估计，最小乘与卡尔曼滤波器的比较。(MATLAB is helpful to realize the sending and receiving of OFDM. The sending end of the specific process is firstly modulated by QPSK, followed by IFFT transformation, and then cyclic prefix is added. The receiving end is an inverse process. Another function of the program is channel estimation, least - multiplication and kalman filter comparison.)

说明：  全国界限SHP，包括九段线，但这个好像只有九段线，可以试用看看。我觉得应该能用。(china.shp,its Chinese map including nine lines,it may help you a lot.)

It s an online daily account. Can use this to key in daily expenses and it will show the summary. This system written using asp and ms access. Good for entry level programmer as reference.

说明：  含BP神经网网络小组作业--对汽油中辛烷值进行检测； 不同神经网络模型的应用对比； Matlab中自带的神经网络工具箱的使用步骤。(Group work with BP neural network -- detection of octane number in gasoline; Application Comparison of different neural network models; The steps of using neural network toolbox in MATLAB.)
