Abstract:This paper proposes a modulation recognizer based on the feature vectors obtained by Intrinsic Time-scale Decomposition(ITD) algorithm and Support Vector Machine(SVM). ITD is employed to extract time-frequency information of communication signals and the obtained feature vectors are transformed into lower-dimensional subspace according to Fisher analysis theory. Multiclass SVM is employed to modulation classification, including 7 types of digital modulation such as 2ASK, 4ASK, 2PSK, 4PSK, 16QAM, 2FSK and 4FSK.… Show more
“…From the perspective of efficient machine learning, it is essential to reduce the computational complexity in feature calculation. Various characteristics of communication jamming in both time-and frequency-domains were analyzed in [10], upon which two classifiers of neural network and decision tree were designed to realize jamming recognition. In [11], a broadband communication jamming recognition method based on graphs and neural networks was proposed.…”
