Abstract:

Visible light communication is innovative and active technique in modern digital wireless communication. In this paper, we describe a new innovative vlc system which having a better performance and efficiency to other previous system. Visible light communication (VLC) is an efficient technology in order to the improve the speed and the robustness of the communication link in indoor optical wireless communication system. In order to achieve high data rate in communication for VLC system, multiple input multiple output (MIMO) with OFDM is a feasible option. However, the contemporary MIMO with OFDM VLC system are lacks from the diversity and the experiences performance variation through different optical channels. This is mostly because of characteristics of optical elements used for making the receiver. In this paper, we analyze the imaging diversity in MIMO with OFDM VLC system. Simulation results are shown diversity achieved in the different cases.
