Performance Evaluation of Dual Polarization Coherent Detection Optical for Next Generation of UWOC Systems

The Underwater Wireless Optical Communication (UWOC) has recently been a unique opportunity for high data rate and moderate submarine distance communication compared with the most common choice such as acoustic wave communications technique. This paper proposes and simulates the design and performance evaluation of the new UWOC system under various conditions of water turbulence. The work has led to an advanced UWOC system which has been presented with appropriate theoretical, analysis and simulation. For the requirement of this target, Coherent Detection Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) and Dual Polarisation technique have been proposed for enabling the next-generation underwater communication systems for to its ability to transmit high data rate and its ability to overcome underwater impairments (absorption, scattering and multipath). The results show significant improvement in Bit error rate (BER) performance of UWOC.
