Software defined radio for RFID signal in Rayleigh fading channel

Software Defined Radio (SDR) based tools of identification may increase with the diffusion of frequency agnostic modes of radio frequency identification (RFID). Similarly, fixed frequency readers may be replaced with interrogators that can operate in any frequency. SDR is a feasible solution for RFID signal, which can perform different functions at different times on the same hardware. Pilot Symbol Assisted Modulation (PSAM) is a good method to compensate for the channel fading effect in wireless mobile communications. In this paper, we first build up a SDR simulation including coding, modulation, Rayleigh fading, decoding and demodulation with match filter. Then, we test the effect of channel model to the RFID signal in receiver with constellation and BER (bit error rate) plots under PSAM.
