Abstract

Problem statement: In this study, optical wireless communication system using visible light is studied for indoor application. Approach: The process started with the calculation on performance of single source white LED where received power, channel DC gain and quality of data transmission (SNR computation) are identified. Through the simulation results, the SNR performance is directly proportional to angle of incident but inversely proportional with the distance. Results: The result at minimum SNR, which is 15dB, the maximum distance, is recorded at 3.0785 m while the other parameter which is angle of incident is recorded at 56.989°. Conclusion: A better performance is needed to improve the reliability of the system because based on the analytical modelling; it proves that this system is expected as indoor communication for next generation.
