I. Introduction
The high-performance system design can greatly benefit from simulating a VLC channel, but needs computationally efficient techniques and models which reflect the properties of the channel parts. Two simulation algorithms, the López-Hernández and the Barry algorithms [1], can be modified to assess the impulse response for indoor VLC channels, for which the Monte Carlo (MC) algorithm [2] is used to research the traversal of the signal for the VLC channel of a 3D workspace irrespective of the number of obstacles created by a simulation environment.
