Integrated system of visible free space optic with PLC

In the recent past, employing visible light generated by white LEDs for indoor optical wireless have been proposed and implemented. Since white-LED is usually distributed over the ceiling for illumination, it is possible to use the ubiquitous powerline cables as a communication medium between other fixed network and LED lights. Some works have been done in this area but because powerline is an unpleasantly medium in case of noise and multipath distortion the existing systems do not have good quality factor. So considerations of these parameters are very important issue to model the actual system. In this paper a review of the integrated system is given while the multipath distortion and noises in the powerline channel are simulated.
