Adaptive Dual Color Visible Light Communication (VLC) System [PDF]
, 2018 In this work, we propose a Visible Light Communication (VLC) system dynamically adapting, through a decision-making process based on a simple fuzzy-logic, the transmitting color selection to the external environmental conditions. Transmitted Signals are opportunisti-cally treated through softwarization approaches by using basic hardware (i.e.
