- 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 802.11a 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. © 2007 IEEE.
