Abstract

New blind carrier frequency offset (CFO) estimation methods based on the correlation function of the subchannel signals are presented for OFDM/OQAM systems. The proposed estimators are robust to multipath effects due to the narrowband property of the subchannels in OFDM systems. The performance of the estimators is evaluated by asymptotic analysis and simulation results. Our results show that methods based on estimation in subchannels have better performance than method based on the signal before demodulation.
