| Abstract: | This paper proposes a timing and frequency synchronization scheme for IEEE 802.11n MIMO-OFDM wireless LAN systems. The proposed scheme is based on training sequence, and exploits multiple-antenna diversity which can significantly improve the MSE performance of the synchronization algorithms. Simulation results show that the proposed synchronization scheme performs well even at a low SNR and can effectively mitigate the effect of Rayleigh fading channel. |
