为降低密集射频识别技术(RFID)网络在多读卡器、多标签环境中的冲突并提高网络容量，提出一种新的多读卡器联合检测方案。该方案将 RFID读卡器密集排列，并应用交织多址技术，使得处于多个读卡器覆盖范围内的标签之间的干扰能够得到解析。这使得读卡器间的联合检测与分集合并成为可能，从而达到更高的信道复用率和网络容量。计算机仿真结果表明在密集 RFID环境中该系统可以在同等或更好误码率条件下实现2~6倍的信道复用率。

This paper proposes a novel multi-reader joint detection scheme for dense Radio Frequency Identification(RFID) networks to reduce interference among multiple readers and tags and improve network capacity. By deploying RFID reader in high density and applying the Interleave Division Multiple Access(IDMA) scheme, signals from multiple tags can be resolved. This allows joint detection and diversity combining among different readers , resulting in better channel reuse. Through computer simulations,it is shown that the proposed system can achieve channel multiplexing by around 2-6 times with equal or better BER in dense RFID environment.
