Visible light communication with Visible light positioning (VLP) has been independently researched broadly because of the wide application and excellent performance of light-emitting diode (LED). In this paper, we describe a new innovative vlc system that has a better performance and efficiency to another previous system. We used the multiple-input multiple-output (MIMO) with the orthogonal frequency division multiplexing (OFDM) technique, which is to enhance the data rate of wireless data transmission. Since we know the multiple transmitter and receiver having different links distances, having various temporal delays, complex channel gain and phase differences are resulting when frequency domain have transformed. In OFDM, each subcarrier, the calculation of the corresponding precoding matrix in the frequency domain for the elimination of multiple interferences. We first considered phase information in the frequency domain, where precoding is uses of intricate patterns, real, channel matrices. Which is used to reduces the channel correlation to achieve better performance? This paper describes a detailed survey of (1) Visible light communication system and characteristics of transmitter and receiver, (2) Modulation methods, (3) SISO, MIMO, MIMO-OFDM, (4) Visible light communication sensing and applications, (5) Visible light communication system architecture design and programming platform
