Modeling and Simulation of the Propagation Characteristics by Underwater Conduction Current Field

Abstract:

Underwater conduction current field communication is a low noise system. It is absolutely to realize the short-distance underwater wireless communication .Compared with underwater acoustic communication, because of the electrical noise underwater is very low, so using underwater current field to realize short-distance underwater wireless communication has a certain advantage. In order to implement the design of conduction current field in underwater communication system better, its necessary to explore and study underwater signal transmission by establishing mathematical model of underwater signal propagation characteristics based on the theory of constant current field and simulating the mathematical model with MATLAB. To fully understand the underwater conduction current field channel characteristics in the actual field environment, we established a simulation model of underwater conduction current field communication channel physical experiment and obtained the amplitude frequency characteristics of the channel based on the external field test data, it laid a solid foundation for the parameter selection of underwater communication system.
