In this paper, the simulator for LED communication channel in indoor was studied. Indoor circumstance was supposed that the shape was hexahedron type and LEDs were located on the ceiling and receiver could be located anywhere. Simulator UI was designed so that upper considered parameters could be easily set. Channel characteristics were composed of LOS(Line Of Sight) and NLOS(Non LOS) LED signal which navigated through indoor after starting at LEDs. Finally channel characteristics which was delay time and attenuated power of received signal was saved as a text file and the result graph was displayed after post-processing.
