Abstract

Visible light communication has received great attention as the superior candidate for radio frequency communication in indoor scenarios, but research on how the location of light-emitting diode lamps affects the achievable rate is rare. In this Letter, the lamp location is optimized with the Adam algorithm for maximization of the average achievable rate, and the Monte Carlo method based on sub-sampling is proposed to reduce the computational complexity of both the achievable rate calculation and optimization process. Moreover, the relationship between room sizes and numbers of lamps is investigated, while the optimal distributions of lamp locations are also illustrated.
