Abstract: The demanding sample rate of classical Turn-on Radio Frequency Fingerprints(RFF) is very high and their receiver structure is quite complex. This paper proposes a novel RFF based on frame synchronization code whose separability is enhanced. The foundation of RFF and typical RFF identification system model are introduced. Based on the derived relation formulation among separability and influencing factors of RFF, the novel synchronization code RFF transform method is proposed. Experiences with IEEE 802.11 wireless interface cards demonstrate that the proposed RFF overcomes the shortcoming of classical Turn-on RFF.

摘要： 经典Turn-on射频指纹对采样率要求很高，并且其接收机结构复杂。为此，通过分析射频指纹的产生机理与典型射频指纹识别系统的基本模型，根据推导射频指纹的可分离性及其影响因素之间的关系解析式，提出一种可分离性增强的帧同步码射频指纹变换方法。采用IEEE 802.11无线网卡进行实验验证，结果表明，该方法可克服经典Turn-on射频指纹的缺点。
