一种ISO 18000-6C协议中FM0回波的解码方法及ARM实现

A decoding method of FM0 echo based on ISO 18000-6C protocol and a realization based on ARM

根据ISO 18000-6C协议中标签反馈信号的规定,提出了一种新的FM0码解码方法,以应用到RFID系统基带解码模块中。并利用三星公司的S3C2440芯片设计了RFID读卡器,对此方法进行了验证及实现。结果显示此方法能够有效地进行FM0解码,克服了传统解码方法的缺点,误码率低、解码效率较高。

According to the provisions of the feedback signal provided by the ISO 18000-6C protocol,this paper proposes a new method of decoding the FM0 echo which is to be used in the RFID system＇s baseband module.This method is verified and realized on a RFID reader based on Samsung S3C2440 chips.The results show that this method can effectively decode FMO.It over comes the shortcomings of traditional decoding and is 1000 bit error rate,more efficient decoding.
