Optimization for link quality and power consumption of visible light communication system

Due to the complexity as well as trade-offs between objectives of the system, it is difficult to design a visible light communication (VLC) system with optimal link quality and power consumption. In this paper, the VLC system design problem is solved by using a multi-objective optimization method. Based on the results of the optimization process, we can determine the parameters to get a VLC system with optimal performance in respect of maximum link quality and minimum power consumption while illumination and other constraints are all satisfied.
