Abstract
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 solutions able to guarantee reliable communication using semi-passive tags jointly with UWB backscatter modulation in the presence of implementation impairments.File in questo prodotto:
