Channel modeling for NLoS visible light networks with integrated sensing and communication

Inspired by the advanced integrated sensing and communi- cation (ISAC) , in this Letter, we explore the non -line -of -sight (NLoS) optical channels formed by reflections from the ground or objects to establish an integrated channel model for simultaneous communication and sensing. The inte- grated channel model can, on the one hand, perceive the changes in the surrounding environment and, on the other hand, determine whether these changes positively or nega- tively affect the quality of communication simultaneously. To validate the effectiveness of the proposed model, from sens- ing, we analyze the impact of various floor materials and visible light communication (VLC) users on the integrated channel; from communication, we characterize the influence of perceived environmental changes on communication per- formance by calculating throughput. Experimental results confirm the capability of the derived model, which can sup- port the design and deployment of VL-based ISAC networks. (c) 2024 Optica Publishing Group
