STPP: Spatial-Temporal Phase Profiling based method for relative RFID tag localization

Many object localization applications need the relative locations of a set of objects as oppose to their absolute locations. Although many schemes for object localization using radio frequency identification (RFID) tags have been proposed, they mostly focus on absolute object localization and are no...
