说明：  matlab仿真LDPC码，对采样点数进行PPM编码，此代码加了保护时隙(The LDPC code is simulated by matlab, and the sampling points are encoded by PPM, which adds protection time slot.)

用MSCOMM控件控制FXPLC全部输出/全部关闭/单独输出(MSCOMM control with full output control FXPLC/All off/single output)

改程序为应用M语言实现对FDMA系统的设计仿真，包括发送接收端以及用户端的仿真(The program is designed to simulate the FDMA system by using M language, including sending and receiving terminal and user side simulation.)

主要是实现调制识别，区分几种常用的数字调制信号。含有两个文件夹 其一为特征参数的仿真；其二为正确识别率的仿真。文件夹key feature simulink中： 运行程序会得到各特征参数之间区分图 从图中可看到特征参数的有效性，见图。 文件夹classification rate simulink中：运行main.m文件 可以得到正确识别率 见图。(It is mainly to realize modulation recognition and distinguish several commonly used digital modulation signals. The simulation of two folders is one of the characteristic parameters, and the second is the simulation of the correct recognition rate. In the folder key feature Simulink: The running program will get the validity of the feature parameters that can be seen from the diagram, as shown in the diagram. Folder classification rate Simulink: running the main.m file can get the correct recognition rate.)
