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)
