说明：  在 matlab 中对无线网络的 ad-hoc 按需距离矢量(aodv)路由协议进行了仿真。 # # 先决条件 * matlab r2017b 或更新 # # 使用更改到该存储库的目录在 matlab。 把剧本叫做”主要”。 高级使用模拟通过网络的流量。 调用“ generatetraffic (packets)”通过网络发送指定数量的随机数据包。 调用“ generatetraffic (数据包，移动)”为数据包提供移动间隔。 对模拟交通进行分析，存储输出并提供给选定的分析函数。 每个图形并返回一个显示信息的图形的引用。(The simulation of ad-hoc on-demand distance vector aodv routing protocol in wireless networks is carried out in Matlab. # # prerequisites * Matlab r2017b or update # # with changes to the repository directory in Matlab. Call the script "the main" . Advanced usage simulates traffic through the network. A call to "generate tactical packets" sends a specified number of random packets over the network. Call "generate RAFFIC packet, move" to provide a migration interval for the packet. The simulation traffic is analyzed, the output is stored and provided to the selected analysis function. Each graph returns a reference to the graph that displays the information.)

三相全桥晶闸管可控六脉动整流电路，通过控制晶闸管导通角可以控制输出直流电压大小(Three-phase full-bridge thyristor controlled six pulse rectifier circuit, by controlling the thyristor conduction angle can control the size of the output DC voltage)

OFDM（正交频分复用）系统以其抗多径衰落和较高的频带利用率，得到了众多领域的广泛应用。本文就OFDM系统中关键技术之一的信道估计技术进行了介绍。并分别叙述了OFDM系统和信道估计的意义，归纳了信道估计的分类，最后介绍了MMSE、LS及其改进信道估计算法并仿真出结果。(OFDM（orthogonal frequency division multiplexing) has been widely used in many areas for its good resistance to multipath fading and high bandwidth efficiency.In this paper,channel estimation,which is one of the key technologies in OFDM systems,were introduced. Then we discuss the significance of the channel estimation and the classification of channel estimation.Finally,we study the algorithms of channel estimation such as MMSE,LS and LMMSE,and further get the simulation results. )
