Analysis and Simulation of Link Performance for Underwater Wireless Optical Communications

This paper investigates how to increase communication distance of underwater wireless optical communication system. In order to analyze the communication distance of UWOC, the performance of optical transmitter and receiver, underwater channel characterization and modulation schemes were discussed. The communication link model was established based the on Beer-Lambert Law. The suitable transmitter power and the maximum communication were achieved in order to achieve communication rate to 1Mbits/s and bit error rate to 10 .This paper not only provides comprehensive understanding of UWOC, but also aims to provide a theoretical foundation for designing the underwater wireless optical communication system and optimizing the system parameters.
