Summary:Latticed hexahedral indoor circumstance was supposed for abstracting the channel characteristics for LED communication. And glass-wall was applied as a one of the surrounding walls for applying actual condition. 2 LEDs are located on the ceiling and 3 PD(Photodiode)s are located in predetermined area, which are divided into reflect multiple received signal characteristics. Mathematical channel modeling was performed for each area, which was named as CM(Channel Model)1, CM2, CM3. Additionally MED and RMS delay spread value was abstracted for each CM. Based on these information, communication simulation was performed considering multi-user condition via spread spectrum technique. Finally optimal modulation parameters were abstracted for Glass-Wall applied LED channel. [PUBLICATION ABSTRACT]
