This paper demonstrates a new high-speed architecture of visible light communication (VLC) system combining with zero cross correlation (ZCC) code of optical code division multiplexing (OCDMA) and novel catenated-OFDM modulation scheme. In order to achieved high spectral efficiency and higher bit rate system for 5G application, we embedded multiband catenated-OFDM modulation technique and OCDMA in VLC design system. Moreover, by employing visible laser diode (VLD) in designing VLC system, we achieved 10 Gbps bit rate at 2.5 dBm input power. We investigate this new combination system design to analyze the bit rate and bit error rate (BER) in 3 m indoor VLC channel propagation.
