Description: A system simulation environment in Matlab/Simulink of RFID is constructed in this paper.
Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system
model,such as phase noise of the local oscillator,TX-RX coupling,reflection of the environment,
AWGN noise,DC offset,I/Q mismatch,etc.Performance of the whole system can be evaluated by
changing the coding method,parameters of building blocks,and operation distance.Finally,some
simulation results are presented in this paper.

Description: These files are my effort for a simple RFID scanner, using the TRF7960 and an Atmel AVR644. The included files only extend to the RFID capabilities of my circuit, and are with realevance to the ISO14443A standard.
rfid.c governs all card communication protocols inmcluding polling times and data format.
rfid_comm.c governs commands for the TRF7960 and also contains code for initialisation, and reading/writing data to registers. The comments explain what needs to be written into the registers for particular modes.
rfid_interupt.c and rfid_timing are simple and govern interupt handling, delays, and resets.
main.c contains the initialisation sequence for the AVR and provides feedback on the i/o lines such as a song from the buzzer and flashing LED s for user feedback. It also contains interupt initialisations for the TRF.
