A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.

常用的几个CSF函数（基于人类视觉特性的频域滤波函数），其说明在PDF文档之中(Top CSF function (the frequency domain filter function based on human visual characteristics ), which are described in the PDF document)

TDMA系统中多用户多业务的无线接入控制和时隙分配算法(TDMA systems in multi-user multi-service wireless access control and time slot allocation algorithm)

matlab的常用命令，对于matlab的初学者非常有用。都是关于matlab的最基本的函数命令。(matlab commonly used commands, very useful for matlab beginners. Are the most basic functions on matlab command.)

最近在书上找的一个程序，可以对微分方程的解法使用(Themselves in line to see a square root to be evaluated on, you can refer to the following)

利用matlab求系统时间响应，用impulse函数和lsim函数对线性连续系统的时间响应进行仿真计算 (impulse function )

给一段1s声音，添加入噪声，输出，然后去除噪声，输出(add noise to a 1s-length voice,excute it ,and remove the noise,and excute it)

说明：  wsn路由，用matlab仿真，具有选簇的功能(WSN routing, simulated with MATLAB, has the function of cluster selection)

这是模式识别中常用的Fisher分类准则的函数，适用于样本类别为两类的情形。返回值是最佳投影方向和投影后的分类阈值。(This is a function of pattern recognition used Fisher classification criteria applicable to the category of the sample for the two types of situation. The return value is the best projection direction and projection classification threshold.)
