摘要：

This letter investigates the sum rate maximization problem in a downlink visible light communication system with simultaneous wireless information and power transfer. To solve this nonconvex sum rate maximization problem, we first transform it into an equivalent convex problem. Then, we provide the optimal condition and propose a low-complexity iterative algorithm, which yields the optimal solution. Numerical results show that the proposed algorithm can achieve good performance.
