Research ArticleOpen accessIn the keywordsAnalytical Study of Signal-to-Noise Ratio for Visible Light Communication by Using Single SourceMohammad Syuhaimi Ab-Rahman, Nurain Izzati Shuhaimi, Luqman Al-Hakim Azizan, Mazen Radhe HassanProblem 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 … …Journal of Computer Science, Vol. 8, Issue 1 · 2 Nov 2011 · 7,479 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Comparison of Experimental and Analytical Study of the Gaussian IntensityDistribution for Light Emitting Diodes BeamMohammad Syuhaimi Ab-Rahman, Luqman Al-Hakim Azizan, Harry Ramza, Zulkifli MusaProblem statement: Wireless communication using white Light Emitting Diodes (LEDs) is the latest research field for next-generation communication. This study studies the comparison of Gaussian intensity distribution of the white LED using experimental and analytical method. The white LEDs are conducted to transmit an audio signal to the receiver. The receiver circuit consist of solar cell connected to the speaker … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,269 accessesView PDF Cite
