• 論文の詳細を見る

• Orthogonal frequency division multiplexing (OFDM) has been adopted in the physical layer of WLAN systems such as IEEE802.11a. In this letter, an efficient preamble structure is proposed to improve the frequency synchronization performance of OFDM-based WLAN systems. The novel preamble effectively multiplexes two different symbols, and the frequency-offset estimation can efficiently utilize the preamble for better estimation performance. Simulation results indicate that using the proposed preamble structure, the frequency synchronization performance can significantly be improved in OFDM-based WLAN systems.
