Abstract [en]

Radio-Frequency-Identification (RFID) with high sensing and positioning capability is the key technology enabler for the vision of the context-aware and location-aware computing towards the Internet-of-Things. However, the existing passive RFID in Ultra-High-Frequency (UHF) based on backscattering scheme can only provide limited ranging resolution and insufficient localization accuracy. Besides, it is sensitive to narrowband interference and multipath environment. Alternatively, Ultra-Wideband (UWB) has been recognized as a promising technology for the next generation RFIDs [1,2]. The Impulse-radio UWB (IR-UWB) implementations employ sub-nanosecond duration pulses without carrier, thus significantly reducing hardware complexity and power consumption. The wideband of the signals provide the potential of fine resolution in dense multipath scenarios. As one of the most attractive characteristics, UWB RFID potentially provides centimeter-level localization accuracy thanks to the ultrashort pulses with high time domain resolution by using time-of-arrival (ToA) estimation of the signal. There has been many works using UWB as active RFID tags for positioning and tracking application [3,4]. Moreover, in order to introduce UWB to passive RFID systems, UHF powered UWB-RFID system with asymmetric links has been proposed in [5]. Based on this UHF/UWB hybrid architecture, the positioning feasibility and ToA estimation has been studied in [6] in algorithm level.
