Abstract

Orthogonal frequency division multiplexing (OFDM) has been adopted in the physical layer of IEEE802.11a WLAN standard. In this Letter, a high-resolution frequency-offset estimation scheme is presented for the OFDM-based WLAN. The scheme efficiently exploits the features of the 802.11a preamble for high-resolution estimation of frequency-offset. Simulation results indicate that the algorithm is much superior to the conventional scheme for frequency-offset estimation in the 802.11a WLAN.
