Power distribution and frequency response performance of underwater optical wireless communications

This paper presents the Monte Carlo simulation to evaluate the power distribution performance and frequency response of underwater optical wireless communication. Comparison is made between collimated beam and diffuse beam in clear water and turbid water. It is observed that by using diffuse beam in turbid water communications can still be established with a coverage area of radius 7 m with a bandwidth of 43 MHz. A higher bandwidth around 158 MHz can be supported by on-axis links.
