主要是实现调制识别,区分几种常用的数字调制信号,包括ASK,FSK,PSK,QAM。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。
文件夹classification rate simulink中:
运行main.m文件 可以得到正确识别率 (Mainly to achieve modulation recognition, distinction of several commonly used digital modulation signals including ASK, FSK, PSK, QAM. One folder contains two characteristic parameters for the simulation second simulation for the correct recognition rate. Folder key feature simulink in: run the program will have the distinction between the characteristic parameters can be seen from the diagram Fig characteristic parameters of effectiveness. Folder in the classification rate simulink: Run main.m file to get the right recognition rate)
