A blind frequency offset estimator for OFDM/OQAM systems Conference Paper

abstract

• 2003 IEEE. Like other OFDM-like systems, OFDM/OQAM systems are very sensitive to carrier frequency offset. A new blind carrier frequency estimator is introduced herein for OFDM-/OQAM systems by exploiting the non-circularity of the received signal. Since the received signal exhibits conjugate cyclic frequencies at twice the carrier frequency offset, a frequency estimator is proposed by maximizing a cost function expressed in terms of the sample conjugate cycocor-relations. Computer simulations illustrate that the proposed estimator is very accurate whenever large observation windows are available, is robust to timing errors and frequency-selective fading effects.
