Radio Frequency Fingerprinting: A Conceptual Study for Addressing Real-World Challenges

While radio frequency fingerprinting has attracted a lot of research interest, especially since the adoption of deep learning based approaches. However, the practicability of these approaches in real-world applications remains the greatest challenge. In this paper, a conceptual study for addressing these real-world challenges is presented. Potential applications and requirements of practical radio frequency fingerprinting systems are proposed. Concepts for addressing individual practicability issues individually are reviewed, and a concept for addressing them simultaneously is derived. Finally, conclusions from the study are drawn, and a look at the future work in the field of radio frequency fingerprinting is presented.
