Frequency Synchronization Using Two-Stage Diversity in OFDM-Based WLAN Systems Sekchin CHANG Publication IEICE TRANSACTIONS on Communications Vol.E89-B No.6 pp.1918-1921 Publication Date: 2006/06/01 Online ISSN: 1745-1345 DOI: 10.1093/ietcom/e89-b.6.1918 Print ISSN: 0916-8516 Type of Manuscript: LETTER Category: Wireless Communication Technologies Keyword: synchronization, diversity, OFDM, WLAN, Full Text: PDF(152.5KB)>>
Summary: 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. | |||||
