Frequency synchronization using two-stage diversity in OFDM-based WLAN systems

Research output: Contribution to journalArticlepeer-review


Orthogonal frequency division multiplexing (OFDM) has been adopted in the physical layer of IEEE802.11a WLAN standard. In this letter, an efficient diversity scheme is presented for better frequency synchronization in the OFDM-based WLAN. The diversity scheme utilizes a two-stage approach to effectively enhance the performance of frequency synchronization. Simulation results indicate that using the algorithm, the performance can significantly be improved in 802.11a WLAN systems.
