Abstract

Des modes de réalisation donnés à titre d'exemple concernent la transmission de signaux déphasés. Un appareil peut comprendre : une pluralité d'antennes ; des circuits de génération de signal configurés pour alimenter la pluralité d'antennes avec une pluralité respective de signaux, la pluralité de signaux étant configurés pour se chevaucher dans le temps et en fréquence et pour porter différentes données, la pluralité d'antennes étant configurées pour diriger la pluralité de signaux vers sensiblement les mêmes directions de transmission et pour provoquer un déphasage prédéterminé entre la pluralité de signaux, le déphasage prédéterminé étant différent pour au moins deux directions de transmission de la pluralité de signaux.
