Trends and Brief Comments on Anti-collision Techniques in Radio Frequency Identification System

Abstract

The anti-collision problems of RFID systems are introduced under the demands of their applications. Firstly in this paper, the operational principle of RFID is briefly addressed and the detection method of collision signals based on Manchester coding is explained. Subsequently, the anti-collision of RFID systems is classified according to the different aspects and their respective solutions are also illustrated. Finally, the perspective of the solutions for transponder collision problems is inferred
