Timing Synchronization of Wireless OFDM LAN Systems
Seung-Kuk Choi · The Journal of the Korean Institute of Information and Communication Engineering · 2009
A timing synchronization method is presented for IEEE 802.11a wireless OFDM system. First the signal detection is achieved by measuring the moving energy of the received OFDM signal in two consecutive windows. By measuring the correlation between the short training signal and received envelope signal, fine OFDM symbol synchronization can be acquired. The variance and average value of the correlation value is acquired. And the theoretical values are compared with computer simulation results.
