802.11/Wi-Fi Channel Estimation
Status: Not yet available - Stay tuned!This talk presents an overview of channel estimation theory and techniques for IEEE 802.11 / Wi-Fi systems. It includes a review of the 802.11 preamble formats, estimation of SISO and MIMO channels, and a discussion of how channel estimates are used in demodulation and decoding. It concludes with recent results in semi-blind channel estimation for 802.11.
