With　the　rapid　development　of　the　Internet　of　Things,　location-based　services　are　becoming　increasingly　important,　especially　in　indoor　environments.　Visible　light　positioning　(VLP)　has　garnered　widespread　attention　due　to　its　high　accuracy,　low　cost,　and　immunity　to　the　radio　frequency　electromagnetic　interference.　However,　traditional　VLP　relies　on　line-of-sight　paths,　making　it　impractical　in　complex　and　dynamic　indoor　environments.　In　this　paper,　we　propose　a　non-line-of-sight　(NLOS)　visible　light　positioning　and　communication　system　based　on　LoRa　modulation　to　address　the　issue　of　link　obstruction.　LoRa　is　employed　to　recover　position　information　transmitted　from　light　emitting　diodes　(LEDs)　over　NLOS　links,　enabling　reliable　communication　under　weak　lighting　conditions.　We　establish　a　geometric　relationship　between　the　LED　and　the　virtual　image　of　the　photodetector　(PD).　Leveraging　the　NLOS　channel　model,　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.　Based　on　experimental　results,　the　proposed　system　achieves　90th　percentile　localization　accuracy　of　less　than　25　and　35　cm　for　the　PD　heights　of　60　and　80　cm,　respectively.　©　2024　Optica　Publishing　Group　under　the　terms　of　the　Optica　Open　Access　Publishing　Agreement.
