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. We used multiple input multiple output (MIMO) with orthogonal frequency division multiplexing (OFDM) technique which is enhance the data rate of wireless data transmission. Since we know the multiple transmitter and receiver having different links distances, having different temporal delays, complex channel gain and phase differences is resulting when frequency domain have transformed. In OFDM each subcarrier, the calculation of corresponding pre-coding matrix in the frequency domain for elimination of multiple interference. We first considered phase information in frequency domain, where precoding are uses of complex matrices, real, channel matrices. Which is used for reduces the channel correlation for achieve better performance. This paper describes a detailed survey of (1) VLC system and characteristics of transmitter and receiver, (2) Modulation methods, (3) SISO, MIMO, MIMO-OFDM, (4) VLC sensing and applications, (5) VLC system architecture design and programming platform.
