Link adaptation for video transmission over COFDM based WLANs

Autor: Ferre, PL, Doufexi, A, Chung How, James T H, Nix, AR, Bull, David

Publikováno v: Ferre, P L, Doufexi, A, Chung How, J T H, Nix, A R & Bull, D 2003, ' Link adaptation for video transmission over COFDM based WLANs ' .

Wireless Local Area Networks (WLANs) such as IEEE 802.11a/g and Hiperlan/2 operate in numerous transmission modes, each providing different throughputs and reliability levels. Link adaptation algorithms proposed in the literature ([1], [2], and [3])
