SPSC Lab Member Daniel Arnitz received the "Award of Excellence 2011" donated by the Federal Ministry of Science and Research. This prize is a tribute to excellent achievements in science. Dr. Arnitz was honored for his PhD thesis on "Tag Localization in Passive UHF RFID". For further information on the award see here.
Short Abstract of the PhD Thesis:
Tag localization in passive UHF RFID has become something of a holy grail since the system was introduced in 2005. First and foremost, it promises salvation for inventory systems, which have to deal with false positive reads and the consequent corruption of inventory lists.
This thesis addresses the problem of passive UHF RFID tag localization, with a focus on supply chain applications. It shows how typical system setups influence the propagation channel and why this creates such a harsh environment for any type of localization. Three tag localization approaches are discussed in detail: phase-based continuous-wave ranging, frequency-modulation continuous-wave ranging, and ultra-wideband impulse radar.
