Description:   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
