Abstract :
Based on the OFDM signal reconstructed by data after decision and channel estimation, a new OFDM carriers frequency offset blind estimation algorithm is proposed. This method can be used to OFDM carrier frequency tracking. This estimator has advantages such as implementation facility, low computations, which only need one IFFT. Simulation results show, this tracking method has very high precision.
