说明：  频谱感知，生成采样频率，进行能量检测，采用matlab算法(Spectrum sensing, generation of sampling frequency, energy detection, using matlab algorithm)

（九宫问题）在一个３×３的九宫中有１－８这８个数及一个空格随机的摆放在其中的格子里，如图１－１所示。现在要求实现这个问题：将该九宫格调整为如图１－１右图所示的形式。调整的规则是：每次只能将与空格（上、下、或左、右）相邻的一个数字平移到空格中。试编程实现这一问题的求解。((Nine-palace issues) in a 3 × 3 of the Nine-palace are 1-8 this 8 random number and the placing of a space in which the cell house, as shown in Figure 1-1. Now required to achieve this issue: the squares adjustment for the right as shown in Figure 1-1 form. Adjustment of the rules: each can only be with the spaces (upper and lower, or left, right) adjacent to a digital flat space. Test Programming to solve this problem.)

说明：  本程序为回波抵消程序，程序中附有解释，很明了，并能到达到消除回波的效果(This procedure for the echo cancellation process, accompanied by explanation of procedures, it is clear, and able to achieve the elimination of echo effect)

QT编写的CAN通讯源代码文件，通讯盒子用的是珠海芯创的can盒(The source code file of CAN communication written by QT. The communication box is the can box of Zhuhai Xinchuang.)

说明：  D2D通信中开环功控的演示，并对其进行编译(Demonstration of open-loop power control in D2D communication)

说明：  基于压缩感知的信道估计算法 包括omp等算法(Channel estimation algorithms based on compressed sensing include OMP and other algorithms)

在OPNET软件上实现路由层和MAC层协议的设计。路由层协议采取LEACH，MAC层协议包括TDMA和CSMA(Achieve routing layer and MAC layer protocols on OPNET software design. Routing layer protocols take LEACH, MAC layer protocols, including TDMA and CSMA)

使用遗传算法优化了阵列天线方向图，亲自打的代码，已验证可使用(Genetic algorithm is used to optimize the pattern of the antenna array, and the code has been verified to be available.)

利用matlab simulink产生两路模拟语音信号，经过pcm编码、时分复用、DPSK调制经过同一个信道单向传输到对应的接收端。常用的三个模块 simulink、通信模块、信号处理模块。包括课程设计报告。(Using matlab simulink produce two analog voice signals through the pcm encoding, time division multiplexing, DPSK modulation over the same one-way transmission channel to a corresponding receiver. The three modules used simulink, communication module, a signal processing module. Including curriculum design report.)
