Next Generation UWOC System Based on MIMO and QAM - OFDM Modulation Techniques

The proliferation of (UOWC) underwater optical wireless communication attributed to its higher data rates than the traditional acoustic communication systems, so it has many potential applications ranging from coastal waters to deep oceans. In this paper, the main focus is to understand the optimum system design, feasibility and the reliability of high data rate underwater optical links due to various propagation phenomena that impact the performance of the system such as channel characterization, modulation schemes and various sources of noise which are due to reflection, diffusing and absorption. Using Multi-Input-Multi-Output (MIMO) as next-generation techniques, in addition, Coherent Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) with quadrature amplitude modulation (QAM) aims to provide the development of new ideas that would help in the growth of future underwater communication, which doable to cut back the consequences of underwater attenuation disturbances. Also, different configurations of MIMO with a CO-OFDM technique are proposed and simulated. The system performance has been evaluated for high turbulence underwater channel. The performance analysis of underwater wireless optical communications using OFDM and MIMO technique are analyzed, and performance comparison between these schemes has been made taking many parameters into thought using (OptiSystem) software.
