In this paper, the rate optimization problem in a relaying visible light communication system with simultaneous lightwave information and power transfer (SLIPT) is investigated, where the power splitting (PS) transmission strategy is adopted. The expressions of the transmission rate and energy harvesting at the target node are derived, based on which, the rate maximization problem is formulated. Then, this problem is solved by optimizing the PS factor, and a closed-form solution is given. Numerical results reveal that the existence of the relay node improves the system performance.
