Reversible data hiding is a technique that embeds important data into cover multimedia, such as image, audio, video, and so on. In the sender side, the data is embedded by the reversible transform, and in the receiver side, the data is extracted by the inverse transform. The carrier can be recovered successfully at the same time. So the good performance makes it popular in data hiding on medical image,...
The paper presents a new algorithm of digital modulation signals based on high order cumulants (HOC) and support vector machines (SVM). The parameters which are picked up from the signals' fourth order and sixth order cumulants are used as the classification feature vectors. Using SVM based on binary tree as classifiers, recognition of the 2ASK, 4ASK, QPSK, 2FSK and 4FSK signals is efficient. The...
A new algorithm based on high order cumulants (HOC) and support vector machines (SVM) for modulation and recognition of digital communication signals is proposed. The new method can identify six digital modulation signals: 2ASK, 4ASK, 8ASK, 4PSK, 8PSK and 16QAM digital signals using fourth and sixth order cumulants of the signals as vectors and SVM based on binary tree as classifiers. The method uses...
