Problems solved by technology

[0003] There are many varieties of existing simulation systems, which are mainly used to carry out studies on the effects of suspended sediment movement, turbulent flow, and laminar flow. There are few factors to consider, and the distance cannot be adjusted dynamically; therefore, it is urgent to adopt a special simulation system for underwater wireless optical communication system to build a more realistic simulation environment of the infield mode, and provide the necessary test guarantee conditions for the in-depth development of underwater optical communication

Abstract

The invention provides an underwater wireless optical communication infield channel simulation device. The device comprises a box body, the box body is a accommodating cavity with an opening in the upper portion, a cover plate is connected to the opening in the upper portion of the box body, a front porthole, a water pump and a water pipe connector of the water pump are arranged on a front panel of the box body, a rear porthole is arranged on a rear panel, a movable partition plate is arranged between the front panel and the rear panel, and an illuminometer is arranged on one side panel. Tap water is injected into the simulation device, aluminum hydroxide, sea salt and the like are added into the water to simulate suspended particles and seawater salinity in the water, and underwater environments under different visibility are obtained; a movable partition plate mode is adopted, so that the problem that dynamic analogue simulation cannot be performed on channel environments with different distances due to the fact that the length of a traditional box cannot be changed is solved; different water flow rates are generated through pump compression, and then the influence of underwaterchannels on optical communication under different distances, different water flows, different communication rates and coding modes is developed, so that an underwater channel simulation model is constructed.

Description

technical field [0001] The invention relates to an underwater wireless optical communication internal field channel simulation device, which is used for carrying out underwater wireless optical communication channel simulation, obtaining relevant channel parameters, and providing guarantee for underwater optical communication system design optimization and system part performance index test verification. Background technique [0002] The transmission environment of underwater optical communication is relatively harsh. The rapid flow of water may cause local changes in the transmission characteristics of the water body, causing the beam to deviate from the original transmission direction instantaneously, affecting the reliability of communication. Channel coding can improve communication quality and increase the operating distance. . How to code the channel needs to be combined with the characteristics of the specific underwater optical communication system, obtained through ...
