Abstract :
We propose a differential space-time coded (STC) radio-frequency-identification (RFID) system where the tag has two antennas and the reader has a single or multiple antennas. In this system, the M-ary phase-shift keying constellation is used, and encoding at the tag and decoding at the reader are simple. Simulation results show that the proposed STC RFID system can achieve a performance improvement over the corresponding non-STC RFID system.
