Abstract: |
An overview is given for the new OFDM based wireless LAN standard IEEE 802.11a. Based on its packet structure, mathematical methods for OFDM symbol timing,carrier Frequency offset and channel estimation are proposed in this paper, which are also the critical technologies in a general OFDM system.[WT5HZ] |
