In this paper, the stability of carrier frequency is used as the fine-grained characteristics of the individual communication transmitter based on the stability analysis. After that, the techniques of extracting frequency stability are well discussed, three approaches are put forward which can extract the fine-grained feature by some special processing the carrier signals. On the basis of analyzing principles of these methods, simulation and practical signals experiments are carried out, and the experimental results show that these approaches are effective. %K Frequency stability %K Fine-grained characteristics %K Feature extraction %K Individual identification
