Robust channel estimation for the OFDM-based WLAN systems with imperfect synchronization
نویسنده
چکیده
Asaneffective technique for combating multipath fading and for high data rate transmission over wireless channels, orthogonal frequency division multiplexing (OFDM) is extensively used in wireless local area network (WLAN) systems to support high-performance bandwidthefficientmultimedia services. In this paper, a robust channel estimation scheme is proposed for the OFDM-basedWLAN systems with imperfect synchronization. The frame structure information, the preamble information, thepilot informationareefficiently utilized in the proposed channel estimation scheme. Simulation results are used to illustrate the performance of the proposed scheme.

In this paper, we propose robust and efficient signal detection and symbol timing synchronization schemes applicable to preamble based wireless systems such as WLAN and WMAN-OFDM. The signal detection algorithm is based on detecting the increase in energy at the beginning of the preamble. For symbol timing synchronization, instead of using conventional normalized timing metric, a new algorithm ...
