Highly sensitive detection technique-based UWOC system

In this paper, a highly sensitive detection technique-based UWOC system is analyzed and investigated. The proposed simulation produced a direct and coherent detection in high turbidity Jerlov water. The laser wavelengths named 450, 550, 650, and 700 nm are utilized with 25 mw to carry the information at a bit rate of 2 Gb/s. The link distance exceeds 650 m in channel water I by 450 nm with PSK-HE-D. For high turbidity in water channel III, the wavelengths 550 and 650 nm produced efficient performance to achieve a good link system with more sensitive detection techniques.
