This m file performs the QPSK transmission and reception.

基于Matlab编写的Rake接收机的基本程序，包含扩频序列的生成，多径延迟等(Written in Matlab based on the basic procedures Rake receiver, including the generation of spreading sequences, multipath delays)

一个2机网络，接入电力系统稳定器，采用时域仿真的方法，用于研究故障后系统频率、电压的波动与恢复过程(A two-machine network connected to power system stabilizer is used to study the fluctuation and recovery of system frequency and voltage after fault by time-domain simulation.)

说明：  对简单闭环系统的PID控制参数进行优化，得到最佳的控制效果。使用时将该文件夹设为matlab默认文件夹，用simulink打开.mdl文件，在命令行窗口输入.txt文档中命令，可以得到优化后的P、I和D参数。(The PID control parameters of the simple closed-loop system are optimized to obtain the best control effect. With using these codes, the folder must be set as the default folder of matlab, then open the. MDL file, and input the commands of . TXT document in the command line window. The optimized P, I and D parameters will be obtained.)

C++和matlab混编示例 (Mixed C++ and matlab examples)

programmed to manipulate the Gray Cyclic Binary Codes.

说明：  微波辐射计的使用,在毫米波的中应用很广,通信领域的使用带来巨大的效益(The use of microwave radiometer, in the millimeter-wave application is very broad, the use of communications has brought huge benefits to)

ddc simulation 进行DDC实现过程的仿真(ddc simulation DDC realization process for the simulation)
