In this paper, we propose a new preamble structure for channel estimation in a MIMO OFDM-based WLAN System. Moreover, both the backward compatibility with IEEE 802.11a system and low overhead are considered for the preamble design. Simulation results show that the proposed preamble has low overhead and is obtained the good performance gain for channel estimation.
