Abstract

As the main way of underwater data transmission, acoustic communication is still limited by the low-level signal-to-noise ratio and channel capacity. The Orbital Angular Momentum (OAM) based wireless optical communication provides a new dimension to data transmission with an expanded channel capacity. We introduce the basic OAM multiplexing communication system, analyze the basic principle of its transmission process, and verify the feasibility of underwater vortex optical communication by simulation. On this basis, the influence of transmission distance and underwater turbulence on the communication system is studied. Our results show that the transmission performance of the system is better in the transmission range of 30 m, and the influence of turbulence on the system performance increases gradually with the increase of signal-to-noise ratio.
