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