说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)

modscan32是modbus/tcp以太网通讯调试工工具,如同串口调试助手一样的工具.， (modscan32 is modbus/tcp ethernet communication tools, debugging tools tools like serial debugging aides.)

说明：  所有有关DOA估计的程序和代码，相当于一个完整的工具箱(All programs and codes related to DOA estimation are equivalent to a complete toolbox.)

基于matlab的PN码的同步仿真，包含详细代码，可以直接运行(Matlab based PN code synchronization simulation, including detailed code, can run directly)

说明：  数字信号QPSK调制，卷积编码，根升余弦滤波器，高斯信道。并画出误码率曲线。(Digital signal QPSK modulation, convolutional coding, root-up cosine filter, Gauss channel. The error rate curve is drawn.)

提供了一种以matlab/simulink为基础方法，采用lqr和滑模变结构控制相结合的控制器，可用于其他模型(Provides a matlab/simulink based method lqr and sliding mode control combined controller can be used in other model)

It is mainly used for ARQ simulation ,such as stop-and-wait

51MODBUS从机程序源码希望对有用的人有用，，(51MODBUS,welcom to here,thank you very mouch.)
