实现Ethercat现场通讯的主从站代码实例(An Example of Master-slave Station Code for Ethercat Field Communication)

基于omnet++4.0版的UWB程序。已经测试可以运行(The UWB program based on omnet++4.0 Edition. Have been tested can run)

说明：  在n个城市建设通信网络，只需架设n-1条线路即可至少包含10个城市，城市数n由键盘录入，城市坐标由随机函数产生小于100的整数(In the construction of communication network in n cities, only n-1 lines are needed to include at least 10 cities. The number of cities n is input by keyboard, and the coordinates of cities are generated by random functions into integers less than 100.)

说明：  该资源为应用GNUradio工具，对USRP的开发，主要实现了频谱感知，以及根据频谱感知的结果进行ofdm通信的功能(This resource is the development of USRP using gnuradio tool. It mainly realizes the function of spectrum sensing and OFDM communication according to the result of spectrum sensing)

FreeModbus_Slave-Master-RTT-STM32-master V1.6

说明：  can总线 多帧传输 接收发送(Can bus multi-frame transmission receiving and sending)

有客户端的聊天软件，可实现网络通讯，对于了解网络编程有帮助(A client chat software, network communications, network programming help for understanding)

实现完整的4CPM(h=1/2)调制解调程序，包括消息序列生成，串并转换，升抽样成形滤波，数字上变频，多项式非线性效应，AWGN信道，到接收端数字下变频，降采样，匹配滤波，接收端基带信号星座图。(Message sequence generation, serial-parallel conversion, up sampling shaping filter, digital upconversion, polynomial nonlinear effects, AWGN channel, to the receiver digital down-conversion, down-sampling, the matched filter, the receiving end the baseband signal constellation.)

MIMO系统的几种信道估计仿真，很有用，已经运行(MIMO system, several channel estimation algorithm simulation, useful, and has been runned)
