Abstract :
This paper proposes a method to estimate the RFID base-band signal frequency offset under the additive white Gaussian noise (AWGN). After theoretical analysis, level threshold setting and signal correlation is introduced to detect frequency offset. The simulation result under MATLAB shows the relationship between the sampled count and accuracy under different SNR.
