Abstract
In this paper, we study carrier frequency offset (CFO) estimation in the uplink of multiuser offset QAM filter bank multicarrier (FBMC) communication systems. A low-complexity frequency-domain CFO estimator using periodical training sequences is proposed. We derive the theoretical mean square error (MSE) for the proposed estimator and computer simulations show that the derived MSE matches the simulated MSE closely. Compared with state-of-the- art time-domain estimators, the proposed estimator achieves better performance with a much lower computational complexity.
