提出两种基于盲源分离方法的标签防碰撞算法，解决标签密集的多天线RFID 系统中的标签碰撞问题。在一个确定的
时隙内， 当发射反向反馈信号的标签数目不超过阅读器天线的数目时， 这些标签可以通过盲源分离算法被阅读器成功识
别；信号，直到所有标签被成功识别出来。仿真结果表明，新算法能使得RFID 系统获得更加高效的吞吐率，能比基于ALOHA
的标签防碰撞算法具有更小的时耗，尤其是当标签数目较大时更加显著。(two tag anti－collision algorithms based on blind source separation (BSS) method are presented to solve the
tag collision problem for dense multi －antennas RFID system in this paper．When the number of tags that transmitting
backscattering signal in a confirmed slot is not exceed the number of antennas of the reader,these tags can be identified
by using blind source separation algorithm．Otherwise,these tags cannot be identified,and they randomly one of other
slots in the same frame and transmit the return signal to the reader until all tags have been identified successfully)

RFID网络*自适应记忆标签防冲突协议
应用背景摘要标签碰撞仲裁无源RFID标签是重要的快速识别。本文提出了一种自适应记忆的标签防碰撞协议这是一个进步在查询树协议。识别标签的效率，我们使用关于标签的读者已经知道。我们如何评估许多冲突可以通过该协议在查询树协议。关键技术无线射频识别（RFID）系统是一种自动识别系统。RFID阅读器识别对象通过与标签具有无线通信唯一的ID信息，并附加到对象。的读者必须能够识别标签尽快。然而，读者或标签的信号碰撞，因为他们沟通在共享无线信道干扰和碰撞快速识别。读者可能不认识所有的由于碰撞的物体。因此，防碰撞协议这减少碰撞和识别标签无论发生碰撞是必需的。
