Abstract
Tag collision may occur in the processing of identification when more than one tag responds the reader inquiry command at the same time,which affects the performance of the RFID system.And the algorithm of under-determined blind separation''s result becomes worse while the number of tags increases.Aiming at these problems,the paper puts forward a novel parallelizable identification anti-collision algorithm based on NMF and Dynamic Frame-Slotted Aloha algorithm.The number of tags in each group can be controlled within the optimum range by selecting a reasonable number of groups,which remains the good condition of the separation of the source signals and the throughput in RFID systems.The algorithm has a very good application value in the field where needs identification of large amount of tags.关键词
