Summary:
This method proposes a novel collision detection methodology in chipless RFID system. The tags are interrogated by a impulse radio ultra wideband signal (IR-UWB). The collided backscattered signal received from the interrogation zone is analyzed in time-frequency plane through Short Time Fourier Transform (STFT). From the time-frequency representation, multiple tag IDs can be easily decoded. The simulation results prove the potentiality of the method as an efficient collision detection technique for chipless RFID systems.
