Abstract :
We develop a novel scheme to track carrier frequency offset in time domain differential modulation and demodulation OFDM systems. Compared with existing methods, this scheme is more bandwidth efficient and easier to implement. Simulation results in the Rayleigh fading channel show that this frequency tracking scheme can work robustly under relatively low SNR conditions.
