  1. 1. Collaborative Exploration with Intermittent Communication : Inferring map information from exploration graphs

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

    Author : Viktor Åkerblom Jonsson; [2023]
    Keywords : ;

    Abstract : Autonomous robots have a substantial presence in today’s society. A presence which increases with each passing year, as more and more problems may be handled by robots. As challenges in the field of Robotics are conquered, the field expands and new challenges appear. READ MORE

  3. 2. 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

  4. 3. Physics-Informed Deep Learning for System Identification of Autonomous Underwater Vehicles : A Lagrangian Neural Network Approach

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

    Author : Badi Mirzai; [2021]
    Keywords : AUV; System Identification; Deep Learning; Physics-Informed Deep Learning; Lagrangian Neural Networks; AUV; System Identifiering; Djupinlärning; Fysik-Informerad Djupinlärning; Lagrangianska Neurala Nätverk;

    Abstract : In this thesis, we explore Lagrangian Neural Networks (LNNs) for system identification of Autonomous Underwater Vehicles (AUVs) with 6 degrees of freedom. One of the main challenges of AUVs is that they have limited wireless communication and navigation under water. 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. Spatially Coupled Codes in Turbo Equalization

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Mgeni Makambi Mashauri; [2019]
    Keywords : Turbo equalization; spatial coupling; waterfall versus error floor; codes on graphs; iterative receivers; LDPC codes in turbo equalization; Technology and Engineering;

    Abstract : In this thesis we investigate the application of spatial coupling in turbo equalization. We show that with spatial coupling we can have a fresh perspective on the trade-off between performance in the waterfall and error floor region often encountered in the choice of codes for turbo equalization.
