Abstract

For oceanographic observation, the Seafloor Observatory Network has the advantages of long distribution distance and wide coverage. However, the observation points of Seafloor Observatory Network are relatively fixed and cannot be changed in time. Underwater mobile observation platform, such as AUV, glider and so on, with flexible motion performance, and carrying capacity of ocean sensors, are excellent platforms for mobile observation. Subject to the underwater communication capability and the constraints of energy supply, underwater mobile observation platforms often cannot acquire data in real time which needs to be acquired after being recovered by the mother ship or shore base. Seafloor Observatory Network has the ability to transmit realtime data. If co mbining Seafloor Observatory Network with the mobile platform, we can expand the range of observation, enhance the initiative and flexibility of observation, and transmit the data to the shore base station through the Seafloor Observatory Network. Wireless communicat ion, which is an ideal technical means of underwater communicat ion, can achieve data transmission, especially multi-point transmission without hardware connected. Although data transmission can be achieved by both acoustic and optical technologies, optical data transmission has obvious advantages in transmission rate, so it is more suitable for Seafloor Observatory Network and mobile platform, which need a huge amount of data to transmit. This paper mainly studies the modeling, analysis and coded modulation method of seawater channel for wireless data transmission in the Seafloor Observatory Network and mobile platform.;For oceanographic observation, the Seafloor Observatory Network has the advantages of long distribution distance and wide coverage.
