Realization of SISO and MIMO-based VLC for Future Communication Systems

Visible Light Communication (VLC) is a technology where light is used to transfer data. Just think of it, where light can be used as a medium of data communication and it is also a source of light (vision). How easy our work would be, the VLC technology is mostly used in indoor communication. The reason for this technology to evolve is the increasing number of crimes. In the present day, the number of internet users are more, there is no work done without the help of the internet. Due to this, the possibility of cyberattacks is more. Most of our personal data and confidential information is lost due to cyberattacks. The companies have faced a lot of financial losses because of it. The data transfer in VLC cannot be hacked easily. It is least prone for the attacks to take placeas communication is mostly indoors. In this paper, we have realized VLC in SISO and $\mathbf{4}\times \mathbf{4}$ MIMO configurations. It is observed that the $\mathbf{4}\times \mathbf{4}$ MIMO configuration outperforms SISO in terms of Bit error rate and Quality Factor.
