  1. 1. Design of Autonomous Underwater Vehicle’s (AUV) Antenna System

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Chengzhuang Zhou; [2021]
    Keywords : AUV Antenna; Printed Dipole Antenna; Broadband Antenna; AUV antenna; Printed dipole antenna; Broadband antenna;

    Abstract : The ocean symbolizes mystery, passion, and power. However, most of the ocean, about 80 %, is unknown to humans. AUVs (Autonomous Underwater Vehicles) provide a platform where terrain mapping, the biodiversity, and the resource survey of the ocean become accessible. READ MORE

  3. 2. Towards Underwater UV Communication- Simulation and Experimentation on Penetration of UV Radiation into Sea water.

    University essay from Blekinge Tekniska Högskola

    Author : Subhash Chandra Ranga; [2021]
    Keywords : Optical Communication; Underwater communication Underwater communication Optical communication; Underwater communication Acoustic communication; Underwater communication Microwave communication; Visible Light Communication; Refractive Index.;

    Abstract : People around the globe are immensely trying to connect using light as carrier due to its low power consumption and high data transfer rates. Sound and microwaves are examples of other carriers that can be used, although they aren't nearly as efficient as light. A method of communicating is using light beneath the surface of the water.

    Keywords : Acoustic communication; temperature; Expendable Bathythermograph; XBT;

    Abstract : This was a thesis that was commissioned by Researcher Peter Sigray at the Royal Institute of Technology (KTH) in Stockholm and was based on an idea by Professor Thomas Rossby, University of Rhode Island (URI). The idea was to further develop the existing Expendable Bathythermograph (XBT), which has been in use since the 1960s. READ MORE

  5. 4. Channel Equalization Using Machine Learning for Underwater Acoustic Communications

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Martin Allander; [2020]
    Keywords : underwater; communications; channel estimation; channel equalization; machine learning;

    Abstract : Wireless underwater acoustic (UWA) communications is a developing field with various applications. The underwater acoustic communication channel is very special and its behavior is environment-dependent. The UWA channel is characterized by low available bandwidth, and severe motion-introduced Doppler effect compared to wireless radio communication. READ MORE

  6. 5. Optical communication with underwater snake robots : Design and implementation of an underwater wireless optical communication system

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion
