Abstract/Notes Data collision problem exists in radio frequency
identification (RFID) system when tabs are present
in the interrogation zone of a single reader at the same
time. Though different anti-collision methods have been
proposed, it still needs further study on how to improve the
identification ability especially in the interference circumstance.
This paper presents a new method based on independent
component analysis (ICA) algorithm. Coded
division multiple access (CDMA) technology is adopted at
the transmitter and the maximum signal to noise ratio is
applied at the receiver of the RFID system. The proposed
method has been verified by computer simulation which
shows that the system can separate different users’ source
data correctly based on ICA algorithm and has better
performance compared with the traditional CDMA
technology.
