说明：  TDMA的opnet仿真模型，比较简单，适合初学者(TDMA the OPNET simulation model is relatively simple, suitable for beginners)

区别去传统的傅里叶变换，对于非平稳信号而言，分数傅里叶变换是一个较好的方法，本程序实现了分数傅里叶变化对LPF类信号的估计。具有较高的学习价值(Different from the traditional Fourier transform, for non-stationary signals, fractional Fourier transform is a better method, this program implements the fractional Fourier transform to estimate the class LPF signal. It has higher learning value)

产生复高斯的白噪声,这和matlab 自带的不一样，容易理解，但是经对比还是和自带的有区别的(AWGN noice we are very nice. please try to run it snd you will find you are good too.)

提供通讯录成员的查询、增加、更新及删除等功能。(Provide contacts membership query, add, update, and delete functions.)

一个简单的verlog HDL教程，内容比较详细，可读性较高。(A simple verlog HDL tutorial, more detailed content, high readability.)

最基础的检测概率；虚警概率；漏检概率与门限的关系。(Energy detection;Single threshold.)

this describe the rouring protocol direct diffusion for wireless sensor network

说明：  利用pluto设备实现qpsk调制与解调，simulink代码文件。(Use pluto equipment to realize qpsk modulation and demodulation, simulink code file.)

实现多项式的加法和减法 并且实现一个多项式的运算(Realize polynomial addition and subtraction and the realization of a polynomial operator)

modbus rtu 校验vb源码，对VB学习者很有帮助(modbus rtu checksum vb source code, useful for VB learner)
