This letter proposed a novel design of the hybrid asymmetrically clipped optical orthogonal frequency division multiplexing (HACO-OFDM) system with cyclic shifted PAM-DMT signals called CSPAM-HACO-OFDM for visible light communication. The transmitted signal generated by the CSPAM-HACO-OFDM system combines the PAM-DMT signals with cyclic shift equivalents by using even subcarriers and the ACO-OFDM signals by using odd subcarriers. Peak-to-average power ratio (PAPR) reduction with remarkably low computational complexity is achieved, and side information is not required. A near-optimal side information detector, which has a similar detection error probability as the perfect-side information detector, is used at the receiver side. Simulation results demonstrate the effectiveness of the CSPAM-HACO-OFDM system in terms of PAPR reduction and average bit error rate.
