The simulation environment is created in Zemax® and enables us to specify the geometry of the environment, the objects inside, the reflection characteristics of the surface materials as well as the specifications of the light sources and receivers. The received optical power and the delay of direct/indirect rays are computed for the specified indoor environment and the corresponding channel impulse response (CIR) is obtained through proper normalizations. Following this methodology, we present CIRs for a number of indoor environments and quantify multipath channel parameters gain for each environment.enginfo:eu-repo/semantics/restrictedAccessConference paper1400034651640031210.1109/ICTON.2014.6876576Visible light communicationsRay tracingChannel modeling2-s2.0-84906739787
