Radio Frequency Identification (RFID) is currently the hottest technology in wireless communication, in which data transmission with extreme low power or even without power in tag. Software-Defined Radio (SDR) plays an important role for a wireless communications system where all the signal processing is implemented in software. In this paper, we first build up a wireless communication simulator including Gray coding, modulation, different channel models (AWGN and Rayleigh fading channels) and demodulation. Then, we test the effect of different channel models to the RFID in receiver with BER (bit error rate) plots under Quadrature Amplitude Modulation. At last, we give detail results of the performance of AWGN and Rayleigh fading channels. We will see that in AWGN channel, the data is degraded by random noise; in Rayleigh fading channel, the data is degraded by random noise and block noise.
