| Abstract: |
| It is reported that the optical wireless communication technology is up to several times of the acoustic communication in data rates, and the advantage of security and anti-interference of optical wireless communication technology makes it widely used in the navy, marine research and underwater engineering, for realizing effective data transmission in real time. An underwater optical channel model which is based on the bio-optical properties is proposed in this paper, and the performance of the underwater optical communications system is evaluated. By simulating a light-emitting diode (LED) and based on underwater optical wireless communication system, it is shown that the method presented in this paper can be used for the different water property simulations, and it provides a basis for the prediction and assessment of the underwater optical wireless communication system design. |
