Abstract
In this paper, a single-input single-output-/multipleinput multiple-output- (SISO-/MIMO-) OFDMA uplink baseband transceiver based on IEEE 802.16e-2005 is proposed. To compensate for the interference of carrier frequency offset (CFO), an inter-carrier interference-based (ICI-cancellationbased) CFO estimator in conjunction with channel estimation and MIMO detector is proposed. Moreover, a low complexity solution for implementation is also provided. Simulation results show that the mean-squareor (MSE) performance of the proposed CFO estimator can be reduced to about one tenth compared to other methods and the bitor-rate (BER) performance of the proposed transceiver is quite close to that of an ideal system that doesn't include CFO compensation. © 2009 IEEE.
