deep learning has been widely used in radio frequency (RF) fingerprinting.
Despite its excellent performance, most existing methods only consider a
closed-set assumption, which cannot effectively tackle signals emitted from
those unknown devices that have never been seen during trainin
通过分析无线设备在物理层中的固有硬件缺陷,基于射频指纹(Radio Frequency Fingerprinting,RFF)技术可以在制造过程中对无线设备进行认证。该文探讨了机器学习和深度学习在 RFF 系统中提取和学习特征的能力以及在真实场景中运行该系统所面临的挑战,同时讨论了当前存在的问题以及未来的研究方向。
