Abstract
In this paper, it is studied anti-collision algorithm based on the transmission protocol for RFID baseband system of the ISO/IEC 18000-6 Type-C regulation and designed the baseband part of RFID reader system using FPGA. To compensate this weak point of the slot random aloha algorithm which must have a long time to be dumped before deciding an appropriate slot size according to the number of surrounding tag, we suggested how to apply Bit By Bit algorithm to be able to recognize the tag when the tag is clashing. The design of the baseband part in the RFID reader system is accomplish by use of the ISE9.1i and I made an experiment on it targeting Spartan2. Construction verification is measured each block through Logic Analyzer and I can verify it has no error. I also compared and analyzed the performance between proposed algorithm and past algorithm and verified the improvement of performance.
