一种应用matlab实现同步码分多址通信的代码，本代码有8个.m文件，互相调用(An application matlab to achieve synchronous code division multiple access communication code, the code 8 m file, calling each other)

此文件夹包含了无线传感器网络中的几个经典模型leach,HEED, 分簇算法(This folder contains several classic models of wireless sensor network leach, HEED, clustering algorithm)

说明：  自己编写的ukf滤波，修改方便 ，注释清楚，适合初学者(The UKF filter written by myself is easy to modify and clear to annotate. It is suitable for beginners.)

压缩感知重建算法集，压缩感知重构算法之压缩采样匹配追踪算法Cosamp算法，用于图像重建或者1维信号的重建。

说明：  这是将波动方程分解为上行波下行波的源程序 把两个源代码放在一起，运行即可了！(This is the wave equation will be decomposed into up-going wave downlink wave source source code of the two together, you can run the!)

The ANPR (Automatic Number Plate Recognition) using ALR (Automatic line Tracking Robot) is a system designed to help in recognition of number plates of vehicles. This system is designed for the purpose of the security and it is a security system. This system is based on the image processing system. This system helps in the functions like detection of the number plates of the vehicles, processing them and using processed data for further processes like storing, allowing vehicle to pass or to reject vehicle. This system also helps to conduct the graphic images of the vehicles which can be further stored in the database in text format reducing size of data to be stored.

说明：  非常好的参考资料，帮助学习时频域分析——s变换(Very good reference material, help to learn time-frequency analysis - S transform)

一个计算声子晶体结构的一维传递矩阵法,包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角，包括压缩比、运行时间和计算复原图像的峰值信噪比,处理信号的时频分析，数据模型归一化，模态振动，包括调制，解调，信噪比计算。

小波包分析提取振动信号中的特征频率，关于小波的matlab复合分析，BP神经网络用于函数拟合与模式识别。( Wavelet packet analysis to extract vibration signal characteristic frequency, Matlab wavelet analysis on complex, BP neural network function fitting and pattern recognition.)

说明：  滤掉低频段和高频段频率，分波段滤波，过滤掉噪声干扰，绘制功率谱密度曲线(Filter out the low and high frequency bands, filter in different bands, filter out the noise interference, and draw the power spectral density curve.)
