Modulation Classification Error Analysis with Phase Offset

概要

• 論文の詳細を見る

• 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 with the phase offset is considered. Two new modulation classification methods based on joint moments of amplitude and phase are proposed with the application to the phase offset. One of the methods uses a difference of a measured moment, and another method uses a shift of signal points. The classification error probability is analyzed to show the superiority of proposed methods.
