RFID Model and Study its Performances

Radio Frequency Identification (RFID) is a generic wireless system which transmits unique identity code using radio waves. This rapidly emerging technology, used to identify objects attached with tags, consists of a reader, tag and wireless channel. The reader & the tag both consist of a microchip and an antenna performs handshaking whenever the both interact. In the present work, a matlab based RFID system is developed incorporating all the relevant ideas. Performance of the system so developed is also verified with some tag code. Performance of the whole system can be evaluated by changing the coding method, parameters of building blocks, and operation distance. Some simulation results are presented in this paper. A Chaotic Noise block is also incorporated in the system in order to realize actual environmental noise conditions as far as possible. Finally, a detailed study on the Bit-Error-Rate (BER) observed under different conditions is carried out using simulated RFID system.
