In consideration of the characteristics of visible light communication (VLC) and orthogonal frequency division multiplexing (OFDM) signal modulation mode, this paper presents some improvements from two aspects of timing metric function and training sequence structure on the basis of the traditional algorithms. In order to solve the problem of the correlation peak plateau and achieve the symbol accurate positioning, the power of the improved algorithm is normalized on the principle of maximum sliding auto-correlation (SAC). The simulation results show that the improved algorithm can obtain a more excellent timing synchronization performance and a lower symbol error rate (SER) in both the additive white Gaussian noise (AWGN) channel and the multipath frequency selective fading (MFSF) channel. Especially under the environment of a low signal noise ratio (SNR), the improved algorithm has overwhelming advantages over other three traditional algorithms.
