通信辐射源个体识别研究现状及发展趋势

Research Situation and Directions of Transmitter Individual Identification Technique

近年来，通信辐射源个体识别技术是通信信号处理领域里的一个研究热点。而细微特征分析和分类器的设计是辐射源个体识别技术的两个重要方面。文章首先从暂态特征提取、稳态特征提取、特征分析与选择这三个方面来介绍细微特征分析的研究现状。然后，分析了分类器在通信辐射源个体识别中的应用现状。最后，结合存在的问题，指出了通信辐射源个体识别技术未来可能的发展方向。

In recent years, transmitter individual identification technique has become research hot spot in communication signal processing. Analysis to communication signal subtle features and design of classifier are two key aspects of transmitter individual identification technique. Firstly research situation of analysis to communication signal subtle features is introduced from aspects of feature extraction to transient signal, feature extraction to steady signal and analysis to feature. Then, application situation of classifier to transmitter individual identification tech- nique is introduced. Finally, the possible research directions of transmitter individual identifi- cation technique are provided briefly, according to current difficulties in individual identifica- tion technique.
