LiFi Transceiver Design for 6G Wireless Networks

Abstract

Due to the dramatic increase in high data rate services and in order to meet the demands of the sixth-generation (6G) wireless networks, researchers from both academia and industry have been exploring advanced transmission techniques, new network architectures and new frequency spectrum such as the millimeter wave, the terahertz, the infrared, and the visible light spectrum. Light Fidelity (LiFi), in particular, is an emerging technology that has been introduced as a promising solution for 6G networks, owing to the large unexploited spectrum, which translates to significantly high data rates. We have witnessed big leaps in the maturity of LiFi technologies in meeting the required demands of 6G networks. In this talk, we focus on various LiFi technologies in the context of 6G networks. Specifically, we consider channel modeling, localization, channel state information acquisition, integration of next generation multiple access techniques and performance optimization. The studied problems are tackled using various tools from probability and stochastic theory, optimization theory, system design and integration theory, and artificial intelligence techniques, such as deep learning and reinforcement learning
