%X Visible light communications is a new type of wireless communications technology. Combined with lighting and communications, it has characteristics of energy efficiency, rich frequency domain resources with no electromagnetic radiation, and so forth. In order to improve the transmission efficiency of optical communication system and resist multipath effect in free space transmission, unipolar orthogonal frequency division multiplexing technique (U-OFDM) was studied in detail. Due to the unipolar characteristics of U-OFDM signal, there is no specific synchronization algorithm. Therefore, a new synchronization algorithm-negative mirror image was proposed. This algorithm can achieve desired effect of synchronization in low signal to noise ratio.
