A performance enhanced miller modulated RFID EPC C1 Gen2 system

초록

In this paper, we present the performance evaluation of the anti-collision algorithm used in the RFI E Cglobal eneration-2 (en2) standard using iller modulation in W environments. In order to improve the anti-collision performance in the noise environment, we use iller sub-carrier modulation rather than F 0 waveforms and we also propose a new scheme for the tag structure equipped with the channel encoder block and the corresponding decoder block in the receiver of the reader system, without changing the basic nature of the E Cglobal en2 standard. By computer simulation, we show that the RFI system equipped with channel coding scheme shows a significant improvement in the anti-collision performance in practical noisy environments.
