产生多种模拟及数字信号，针对多种调制信号进行有效地调制识别-modulation classificationforsignals such as：PSK,MPSK,FSK，MFSK，FM,AM,PM，SSB,DSB,AM

利用MATLAB gui 编的短波通信系统，录制一段语音信号，分别通过AM SSB DSB 等调制信号，加入噪声，然后解调出来，可比较各种调制解调方式的优劣。-Use MATLAB gui compiled shortwave communication system, record a voice signal, respectively, by AM SSB DSB modulated signal, etc., added noise, then demodulated, you can
