Modulation techniques and power analysis in wire-branched optical LOS channels

Today, Optical Wireless Communication technologies (OWC) are one of the most important alternative communication methods for radio frequency (RF) communication. Due to the limited Radio Frequency (RF) communication, the demand and need for high-speed wireless communication systems has been increasing day by day, especially in recent years. Radio frequency (RF) communication systems; Radio frequency (RF)-based communication has caused a serious spectrum problem in recent years due to the presence of limitations such as uncontrolled radiation emission, limited bandwidth, regulated frequency and not being able to address the increase in the number of mobile users. Besides, Visible Light Communication (VLC) compared to Radio Frequency (RF), Visible Light Communication (VLC); It uses higher frequency bands in the visible light spectrum for the transmission medium. Due to its bandwidth advantage, VLC using the visible light spectrum is more advantageous as it offers strong resistance to high electromagnetic interference and high transmission speed. In this respect, optical Wireless Communication Systems (OWC) are seen as a promising solution for next generation wireless communication systems.
