La transmission de données sans fil est omniprésente et le trafic mondial des données connaît une croissance rapide. Les ressources actuelles du spectre des radiofréquences (RF) sont de plus en plus saturées, donc le système de communication sans fil basé sur les RF ne pourra pas faire face aux exigences croissantes du trafic à l’avenir. Des techniques telles que la transmission et la réception multiples (MIMO) ont fait l’objet de nombreuses études approfondies. Cependant, ces techniques restent insuffisantes pour répondre à la croissance rapide du trafic de données sans fil. L’avènement de l’infrastructure d’éclairage LED représente une énorme opportunité pour le développement des communications par lumière visible (VLC). Elles utilisent les LED pour transmettre des données sans fil à haut débit.L’objectif principal de cet ouvrage est d’améliorer les performances des systèmes VLC pour des applications intérieurs en termes d’illuminance, de puissance reçue, de rapport signal sur bruit (SNR) et de débit, en proposant un nouvel arrangement des LED (3D). L’étude porte également sur l’effet des paramètres émetteur/récepteur sur le débit de données dans un système 4x4 MIMO-VLC.
