Abstract

Dans divers modes de réalisation, la présente invention concerne diverses définitions de spectre de signal destinées à être utilisées dans des réseaux sans fil. Par exemple, l'invention concerne des définitions de spectre de signal de multiplexage par répartition orthogonale de la fréquence (OFDM, "orthogonal frequency-division multiplexing") à multigigabit directionnel amélioré (EDMG, "enhanced directional multi gigabit"), par exemple, pour une utilisation en connexion avec une transmission à sortie et entrée uniques (SISO, "single input single output") avec liaison de canal. Dans un mode de réalisation, le spectre de signaux OFDM peut comprendre des données, des sous-porteuses pilotes, zéro courant continu (CC) et zéro sous-porteuse de bande de garde (GB, "guard band"). Dans un autre mode de réalisation, les données et les sous-porteuses pilotes peuvent définir le nombre total de sous-porteuses occupées dans le spectre de signaux OFDM.
