High-speed, reliable, flexible, and cost-effective underwater wireless communication systems have a wide variety of use in scientific, civilian, and commercial domains. Visible Light Communication (VLC) seems to be a promising candidate in satisfying majority of the requirements listed above. From this perspective, VLC could easily be deployed in heterogeneous wireless networking scenarios with high quality of service (QoS). Therefore, in this study, a 3GPP LTE based complete underwater VLC (UVLC) system is implemented. The performance of UVLC system employing ACO-OFDM modulation technique is practically tested by taking channel estimation and synchronization into account. Also, the effects of varying OFDM parameters on the system’s signal-to-noise ratio (SNR) and the bit-error-rate (BER) performances are studied. The implementation is tested for QPSK and 16-QAM modulation techniques supporting both 128and 1024-points FFT configurations which correspond to data rates of 1.92Mbps and 15.36Mbps, respectively. Experimental results show that BER could be reduced down to a level on the order of 10 to the power of 6.
