    • 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 ...
