31175278moulationclassification
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.)
