Abstract :
This paper proposes an architecture for an RFID receiver which allows a number of RFID tags with oscillators of low frequency stability to be accommodated within the same RFID cell. The RFID tags can transmit at carrier frequencies anywhere within a wide band of 30 MHz centred on 5.8 GHz. The synchronisation technique uses a carrier frequency estimator which is implemented using SAW dispersive delay filters. The carrier frequency estimator uses the spectral properties of the received signal to estimate the carrier frequency.
