| Abstract | Abstract. Radio Frequency Identification (RFID) provides a non-line-of-sight and contactless approach for object identification. In the supply chain, objects are usually assembled into a group and RFID system enables us to quickly identify a group of objects. However, RFID system only provide the identified objects ’ ID, unable to provide the missing objects ’ IDs. This paper concerns the problem of missing objects detection and missing unique IDs recovery. In supply chain, a traditional method of items lost detection is encoding a group of objects ’ ID before the shipment, and decoding when examine the integrity of the objects. In this paper, we propose a new scheme for missing objects detection and missing IDs recovery, which is called Linearly Independent Vectors Based Group Coding, abbreviated LIVGC. A numerical simulation reveals that the proposed method have higher recovery rate (>20%) than the EGC scheme in the same length of redundancy code. |
