Abstract: The effects of carrier frequency offset (CFO), sampling frequency offset (SFO), and channel responses on the received samples are analyzed and explored to develop the turbo joint channel estimation, synchronization and decoding scheme for coded MIMO-OFDM systems. For burst transmission, with initial estimates derived from the pre-amble, the proposed scheme can operate without the need of pilot tones during the data segment. Simulation results also show that the proposed scheme offers fast convergence and low mean-squared-error (MSE) over quasi-static Rayleigh multi-path fading channels, and can be used in a coded MIMO-OFDM transceiver in presence of multipath fading, CFO, and SFO to achieve a bit-error-rate (BER) performance comparable to that in an ideal case of perfect synchronization and channel estimation after three iterations. ©2008 IEEE.
