A Control Method to Reduce Interferences and Collisions between Multiple RFID Tags and RFID Readers

Radio frequency identification technology (RFID) is one of the fastest developing
technologies today. Although it has significant performance in use of Auto-ID
applications, the presence of multiple tags in a RFID system can lead to
interferences between each tags which is called Collision. There are many method to
overcome this issue and this project introduces the use of DS-CDMA technique to
overcome this issue. The Simulink simulation environment is used to simulate the
use of DS-CDMA in RFID system. The results obtained clearly show the concept of
this method is leading to a solution for RFID collision issues. However, the further
improvement in simulations and concept of the method is most recommended in
future project work.
