Nowadays, passive and semi-passive wireless devices are increasing their appeal, particularly in the new scenario of the Internet of Things, thanks to their low complexity and low energy consumption. In this context, radio-frequency identification (RFID) and radar sensor networks (RSNs) are rising interest when the localization of (semi-)passive tags (without active transmitters) and moving passive...
UWB backscatter modulation paves the way to next generation RFID systems. This solution overcomes the main limitations of the current UHF technology in terms of robustness to multipath fading and localization capability. On the other hand, the design of UWB RFID systems presents several new aspects to deal with such as clutter, multi-user interference, and clock drift. This paper illustrates some...
