Abstract

In this paper, two different methods for identification and separation of analog and digital modulation,
is presented. One of these methods is based on spectral correlation function and the other is based on high
order moment and dimension reduction of modulation; for detection and recognition of digital and analog
modulation. After a careful survey on these two methods, a synthetic method with high detection resolution
and usable in COMINT systems is presented. Simulation result shows that the proposed method outperforms
traditional methods in low SNR for detection of the type of the modulation. Moreover, the proposed
method is efficient for detecting the type of high order QAM, phase and frequency modulation. In addition,
numerical results show that the proposed method has acceptable complexity performance, compared toother
methods.
