    • Modelling and Simulation of Ego-Noise of Unmanned Aerial Vehicles 

      Insausti, Xabier; Hogstad, Bjørn Olav; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2020)
      In this paper, we develop a simulation model for the ego-noise of unmanned aerial vehicles (UAVs). The ego-noise is composed of spike noise and background noise. The spike noise is modelled by a finite sum of sinusoids, ...

    • On the Complexity Reduction of Coding WSS Vector Processes by Using a Sequence of Block Circulant Matrices 

      Gutiérrez-Gutiérrez, Jesús; Zárraga-Rodríguez, Marta; Insausti, Xabier; Hogstad, Bjørn Olav (Journal article; Peer reviewed, 2017)
      In the present paper, we obtain a result on the rate-distortion function (RDF) of wide sense stationary (WSS) vector processes that allows us to reduce the complexity of coding those processes. To achieve this result, ...
