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)

电子标签防碰撞是RFID 系统中一个关键问题。在射频识别系统中．当阅读器作用范围内有多个标签同时向阅读器发送数据时，会产生冲突，必须采用一种防碰撞算法解决这种冲突。在分析典型的二进制及动态二进制防碰撞算法基础上，采用了一种新的防碰撞算法。经实验证明，该算法能有效解决射频识别系统中多目标识别的防碰撞问题。(Tag anti-collision RFID system is a key issue. In the radio frequency identification systems. When the reader within the framework of the role of multiple tags simultaneously send data to the reader, it will create conflict, you must use a anti-collision algorithm to solve such conflicts. In the analysis of a typical binary and dynamic anti-collision algorithm based on the binary, using a new anti-collision algorithm. The experiments show that the algorithm can effectively solve the radio frequency identification system, multi-target recognition of the anti-collision problem.)
