In　this　work,　we　propose　a　non-line-of-sight　(NLOS)　visible　light　positioning　system　based　on　LoRa　modulation.　Initially,　a　visible　light　communication　(VLC)　subsystem　based　on　LoRa　modulation　is　designed　to　receive　the　transmitter＇s　position　in　NLOS　links.　Subsequently,　leveraging　the　NLOS　channel　model　and　the　geometric　relationship　between　light　emitting　diodes　(LEDs)　and　the　virtual　image　of　the　photodetector　(PD),　we　derive　the　relationship　between　the　received　signal　strength　and　the　distance　from　LEDs　to　the　virtual　image　of　the　PD.　Through　this　relationship,　the　trilateration　method　is　applied　to　calculate　the　position　of　the　receiver.　Experimental　results　demonstrate　that　the　average　positioning　errors　of　the　system　are　16.27　cm　and　20.97　cm　when　the　PD　height　is　60　cm　and　80　cm,　respectively.　©　2024　IEEE.
