Abstract

In this paper, different frequency offset estimation schemes and their combinations are investigated for IEEE 802.11a based Wireless LAN. Their performance has been compared in terms of deviation and required hardware implementation complexity. Our simulation results show that, by using the short sequences alone, the estimation error can be less than 2% of the sub-carrier spacing for a given SNR of 15 dB. Two-stage frequency offset compensation by using short sequences for coarse estimation followed by long sequences for fine estimation may not give significant improvement due to some independent estimation error effects.
