Abstract: This paper proposes and demonstrates an arbitrarily tunable multi-frequency pulse modulation scheme based on an active fiber loop, which effectively suppresses the interference fading effect ...
The Shrinking Airwaves Wireless microphones used to have plenty of room to breathe. For decades, most systems operated comfortably within the UHF television range from 470-806 MHz. These frequencies ...
For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from ...
Abstract: Radio frequency fingerprint identification (RFFI) is a promising authentication mechanism for physical-layer security. In this article, we thoroughly validate the feasibility of using RFFI ...
