摘要：

Carrier frequency synchronization is important in MIMO-OFDM systems. Any carrier frequency offset will cause a loss of subcarrier orthogonality which results in ICI and hence performance degrades severely. In this paper, a preamble structure for MIMO-OFDM systems is proposed. Based on the structure, the carrier frequency synchronization algorithm in burst data transmission for MIMO-OFDM systems is improved. The paper investigates the value of the improved algorithm with transmit and receive diversities for carrier synchronization in MIMO-OFDM systems. The simulation results show that the carrier synchronization performance in MIMO-OFDM systems with the improved algorithm exploiting transmit and receive diversity is efficient and robust, especially in low signal-to-noise ratio condition.
