Passive UWB-RFID technology represents an emerging solution capable of guaranteeing extremely low energy consumption and high-accuracy localization at the same time. One of the most critical tasks is the acquisition of the tag code at reader side, which can be complex, time-and resource-consuming when multiple UWB tags are deployed. This letter proposes a simple and effective approach, based on a specific assignment strategy of the tag code, which drastically simplifies code acquisition by guaranteeing high tag detection performance. A real system implementation adopting this strategy is shown to prove its feasibility in terms of real-time multiple tags detection and localization.
