Rigorous modeling for visible light wireless access based on environment friendly illuminance

Visible light wireless access (VLWA) technique based on environment friendly illuminance is in progress. To the best of our knowledge, the efficient modeling of corresponding indoor channel including sophisticated reflection has not been proposed. In this paper, a rigorous and efficient channel modeling scheme, named independent reflection interaction characterization (IRIC), is presented which can be used to account for reflection of any order. And simulation results show that this scheme can characterize the VLWA channel model in less than 10 seconds in a medium-sized room with up to 6 order reflection considered for analyzing received optical power and illuminance function.
