Özet

Parallel to the development of technology, the interest in different protocols in communication systems is increasing. In this context, visible light communication (VLC) systems that promise high data rate, unused spectrum and high data security attract attention and are promising for the future. The main problem to be overcome in visible light communication systems is known as the necessity of increasing the channel capacity in order to spectrally overlap the Light emitting diodes (LEDs) used as transmitters and to serve many users. Wavelength Division Multiplexing (WDM) and Optical Time Division Multiplexing (OTDM) techniques can be suggested as solutions to VLC problems. In this study, the advantages of WDM and OTDM techniques were investigated and a reference hybrid OTDM/WDM VLC system was designed. The performance of the system designed using the OptySystem 14.0 simulation software was analyzed over the Eye diagram, Q factor and Bit Error Rate (BER) values.
