There is dramatic increase in wireless traffic due to the demand of high speed internet services such as M2M, Cloud based services, video conferences, online gaming, web browsing etc.This huge global demand of bandwidth find it complex to accomodate in the existing RF spectrum. So alternative wireless technologies that will ease this 'Spectrum crunch' need to be implemented as soon as possible. The technology must be able to provide ultra high data rates to end users. Visible Light Communication, which is a subset of Optical Wireless communi-cation technology have unregulated, unlicensed bandwidth.It can provide dual function of illumination and communication at high data rates.This paper gives a study on performance enhancement of MIMO VLC Systems.
