Performance analysis of optical wireless communication system using pulse width modulation

Optical wireless communication has emerged as a promising complementary technology for Radio Frequency technology. Reliability and survivability of solid state lighting devices has attracted researchers and is gaining attention as they provide synergistically illumination and communication. Furthermore optical wireless communication is environmental friendly and also helps in energy conservation. In this paper various parameters for visible light and infrared link such as link accuracy, noise immunity have been studied. A simple algorithm has been described for localization and tracking for a full duplex optical wireless communication system.
