In this paper, a robust channel estimation scheme is proposed for the OFDM based wireless local area network systems. The proposed channel estimation scheme has been done targeting the IEEE 802.11a standard [, but it can be extended to other packet-based OFDM systems. A robust channel estimation scheme is proposed for the OFDM-based wireless local area network systems. Performance evaluation shows that the WLAN system with the proposed channel estimation scheme is with practical system performance under harsh fading channel.
