Abstract
The automatic modulation identification for communication signals is an important problem in the intercepted signal processing and widely used in non-cooperation communication of military and commercial. This paper proposes a method that based on the second and fourth order cumulants of received signal which can classify digital modulation signal, which can suppress the Gaussian white noise, so we can identify six digital modulation signals: 2ASK、2PSK、4PSK、 2FSK、4FSK and 16QAM. In the end, the computer simulation that the automatic identification of modulation signals based on high order cumulates is reasonable.
