A new improved MIMO-OFDM synchronization algorithm is proposed in this paper. Frame synchronization is performed by the uniqueness of correlating peak value of symmetric sequence. Fractional frequency offset estimation is processed by repeat sequence after frame synchronization. In frequency domain, integer frequency offset estimation is performed based on energy detection in virtual carriers. The performance comparison of the proposed algorithm and Mody’s algorithm by using computer simulation illustrates and verify the superior performance of the proposed algorithm. Especially in bad channel environment, the proposed algorithm also satisfy synchronization requirement.
