Abstract：In indoor visible light communication systems,to ensure that multiple users in different directions within a room can receive good communication quality and achieve uniform coverage of optical power on the receiving surface,it is necessary to rationally optimize the layout of light sources.Reasonable light source layout design can achieve stable signal transmission,improve the signal-to-noise ratio of the transmitted signal,reduce inter-symbol interference,and contribute to an increase in communication speed in visible light communication systems.This paper briefly introduces the proposal,development and unique advantages of visible light communication,and gives a general overview of the principles and channel models of visible light communication systems.It summarizes and compares the layouts and designs of light sources in visible light communication systems,and explains their development trajectory and research progress.Finally,it concludes by summarizing the development direction and trends in the design methods of visible light communication layouts.
