High Spectrum Efficiency DFT-S OFDM Visible Light Communication Based on Interleaved Allocation and Phase Reversal Coding and Hybrid Pre-Equalization

A novel interleaved allocation, phase reversal coding and hybrid pre-equalization scheme is proposed in DFT-S OFDM VLC system. A 64QAM signal at 440M baud, 256QAM signal at 325M baud over 1-m transmission is experimentally demonstrated.
