| Abstract(in English) | When a carrier frequency and a phase are not recovered with the sufficient accuracy in a receiver, a signal point rotates in a vector diagram. The signal point rotation causes a phase offset. In this paper, the optimal modulation classification method based on cosine moments with the phase offset is considered. At the front end of modulation classifier, the small signals are rejected, and only the large signals are fed into the classifier to improve the performance. Numerical results of the classification error probability show the effectiveness of proposed methods with phase offset for QAM classification. |
