    • Distributed fusion in underwater sensor networks: Fusing bearing information 

      Otnes, Roald Wilhelm; Zetterberg, Per; Blouin, Stephane; Nordenvaad, Magnus Lundberg; Austad, Håvard; Dombestein, Elin Margrethe Bøhler (2019)
      In underwater sensor networks, distributed data fusion may be more efficient than centralized fusion because the limited data transmission capacity can make it difficult to collect all required sensor information at a ...

    • Ultrawideband underwater acoustic communication channels 

      Walree, Paul van; Otnes, Roald Wilhelm (2013)
      Traditional channel models for communications research are designed for narrowband systems. Underwater acoustic communication systems use a bandwidth that is not small compared with the center frequency of the signal and ...

    • Underwater Acoustic Communications: Long-Term Test of Turbo Equalization in Shallow Water 

      Otnes, Roald Wilhelm; Eggen, Trym Haakon (2008)
      Acoustic telemetry sea trials lasting for three months with experiment periods of 7 h have been carried out, using a turbo receiver. The communication channel is shallow; the depth is approximately 10 m, and the range is ...

    • Validation of replay-based underwater acoustic communication channel simulation 

      Otnes, Roald Wilhelm; Walree, Paul van; Jenserud, Trond (2013)
      This paper discusses validation methods for underwater acoustic communication channel simulators, and validates direct and stochastic replay of underwater acoustic communication channels as implemented in a channel simulator ...

    • The Watermark benchmark for underwater acoustic modulation schemes 

      Walree, Paul van; Socheleau, François-Xavier; Otnes, Roald Wilhelm; Jenserud, Trond (2017)
      Watermark is a freely available benchmark for physical-layer schemes for underwater acoustic communications. It allows researchers to test and compare algorithms for the physical layer under realistic and reproducible ...
