摘要
调制制式的自动识别是非合作通信系统接收机设计中的重要研究课题.着重讨论了利用特征参数对几种基本调制制式(DSB、FM、PM、2ASK、2FSK、2PSK)的自动识别问题,对叠加了高斯白噪声的通信信号的自动识别进行了计算机仿真.实验结果表明,此种识别算法具有较为理想的识别效果.
Automatic modulation recognition is an essential part in receiver design of non-cooperative communication system.The recognition basic modulation styles(DSB,FM,PM,2ASK,2FSK and 2PSK) is discussed by using characteristic parameter and a computer simulation is made on communication signals in Gaussian hot noise. The result of the experiment demonstrates that this recognition algorithm can obtain a better recognition result.
