As wireless platforms grow in popularity and store valuable information, their security becomes increasingly important. Specific emitter identification (SEI) is a novel means of enhancing the security of wireless networks. Thus, an automatic SEI system with good performance is meaningful. In this paper, a novel method for SEI based on singular spectrum analysis (SSA) is proposed. It uses SSA to analyze the transient signals and extract features for identification of mobile phones. A complete identification system is presented and its performance is evaluated by volume experiments, which show that the proposed method is efficient even at a reduced signal to noise ratio.
