    • Performance analysis for industrial wireless networks 

      Zdravkovic, Nemanja M. (Doctoral theses at NTNU;2017:64, Doctoral thesis, 2017)
      Industrial wireless networks operate in harsher and noisier environments compared to traditional wireless networks, while demanding high reliability and low latency. These requirements, combined with the constant need for ...
    • Permutation Spreading and Alamouti Space-Time Coding for DSSS MIMO Systems in Frequency Selective Rayleigh Fading Channels 

      Kristoffersen, Marius Grønby (Master thesis, 2021)
      Denne masteroppgaven presenterer nye metoder for to sender-diversitetteknikker med bruk av direkte-sekvens spredet spektrum i en fler-inn fler-ut frekvensselektiv Rayleigh modellert kanal. Et problem i denne settingen er ...
    • RSS-Based Secret Key Generation in Wireless In-body Networks 

      Awan, Muhammad Faheem; Kansanen, Kimmo; perez, Sofia; García-Pardo, Concepción; Cardona, Narcís (International Symposium on Medical Information and Communication Technology;, Chapter, 2019)
      Secure communication is considered as an integral part of next generation wireless implantable medical devices. In this work, we provide the symmetric cryptographic key generating approach by exploiting the randomness in ...
    • Self-Organizing Networks (SON): TD-ICIC Implementation In a Network Simulator 

      Christiansen, Thomas F. (Master thesis, 2014)
      Co-channel interference is becoming a real headache for operators when deploying HetNets but a solution presents itself in the form of inter-cell interference coordination (ICIC). One form of ICIC is called almost blank ...
    • Smart Antennas for Interference Suppression 

      Langan, Torstein Mellingen (Master thesis, 2021)
      En smart antenne bestående av et rektangulært antenna array og en adaptiv stråleformer har blitt designet, og dens interferensundertykkende egenskaper har blitt undersøkt. En trådløs sakte utviskende bredbånskanal med ...
    • Study and Performance Analysis of LTE MAC Schedulers for M2M 

      Ferri, Giovanni (Master thesis, 2016)
      Cellular systems are forecasted to play a fundamental role in the future Machine-to-Machine scenario. The 3GPP LTE networks appear to be the de facto standard for machine type communications. Beside opportunities given by ...
    • Survey on Communication and Networks for Autonomous Marine Systems 

      Zolich, Artur Piotr; Palma, David; Kansanen, Kimmo; Fjørtoft, Kay Endre; Sousa, João; Johansson, Karl H.; Jiang, Yuming; Dong, Hefeng; Johansen, Tor Arne (Journal article; Peer reviewed, 2018)
      The rapid development of autonomous systems and Information and Communications Technologies (ICT) create new opportunities for maritime activities. Existing autonomous systems are becoming more powerful and utilise the ...
    • Waveform Design for Software Defined Multifunctional RF Systems 

      Åsheim, Anders (Master thesis, 2017)
      In this thesis, a study of multifunctional radio frequency (RF) systems implementing radar, communication, and electronic warfare (EW) is presented. Development of low cost and highly adaptable software defined radios ...
