채널 에러가 존재하는 RFID 시스템에서 효율적인 태그 추정 방법과 충돌 방지 방법

In RFID systems, a tag is easy to cause channel error. But anti-collision method in channel error condition have not been studied up to recently. In this paper, we propose an efficient estimation method and an effective tag anti-collision method in channel error condition. Simulation results show that the proposed estimation and anti-collision algorithm consumes 20-25% less time slots than the binary tree protocol and dynamic framed slotted ALOHA (DFSA) in channel error condition.
