Abstract :
In order to enhance the efficiency of supply chain, Radio frequency identification (RFID) technology is used to label every cargo. Logistics center (warehouse) is the important node in supply chain. The RFID application in warehouse is complicated. The environment influence and multi-tags collision would make the reader lost targets. It is desired to raise the detect accuracy and detect speed of RFID reader. In this study, we propose multiple antenna beam former algorithm based on SDMA (Space Division Multiple Access) theory to get rid of the multi-tags interference in warehouse with RFID technology. The simulation results show that proposed algorithm can enhance the detect accuracy of RFID reader. It will become an effective tool in warehouse management. Further more, the RFID reader using multiple antenna beam former algorithm will save energy.
