The assessment of Turkey as a soft power :2009-2014
Rapid development in technology and increasing necessity to reach information instantaneously saturates RF bands rapidly. Because of that it can be seen that we are gradually approaching upper limits of the band. it can said that operating beyond that upper limit would be hard and unfeasible for 5th generation mobile systems (5G). At this point it is needed to develop alternative telecommunication systems to RF technology. VLC could be the most appropriate and appealing solution for researchers due to its unregulated visible light band. in this context determination of the real VLC channel models would play vital role on bit error rate performance of the communication systems. The main objective of this thesis is to introduce this novel and interesting topic to the the researchers and investigating performances of SiSO and MiMO OFDM based VLC systems in realistic channel models obtained in Zemax environment. Besides novel transmission model is proposed in the thesis and analyzed and simulated in great detail. Obtained performances of SiSO-MiMO OFDM based VLC systems are compared with reference systems and conclusions are offered about the results.
