On the Consistency of Non-Stationary Multipath Fading Channels with Respect to the Average Doppler Shift and the Doppler Spread
(IEEE Wireless Communications and Networking Conference : Proceedings;, Journal article; Peer reviewed, 2017)This paper is concerned with the consistency of non-stationary multipath fading channels. We introduce conditions under which a channel model is consistent w.r.t. the average Doppler shift and the Doppler spread. The ... -
Using game elements to increase students’ motivation for providing peer assistance
(Master thesis, 2017)Abstract Peer assistance is a support system where people of equal status help each other solve problems. It is also a recognized method within education where students support each other with their assignments. The ... -
A Random Trajectory Approach for the Development of Nonstationary Channel Models Capturing Different Scales of Fading
(Journal article; Peer reviewed, 2017)This paper introduces a new approach to developing stochastic nonstationary channel models, the randomness of which originates from a random trajectory of the mobile station (MS) rather than from the scattering area. The ... -
Topology Design to Increase Network Lifetime in WSN for Graph Filtering in Consensus Processes
(European Signal Processing Conference (EUSIPCO);25 2017, Journal article; Peer reviewed, 2017)Graph filters, which are considered as the workhorses of graph signal analysis in the emerging field of signal processing on graphs, are useful for many applications such as distributed estimation in wireless sensor networks. ... -
Modelling and Analysis of Non-Stationary Multipath Fading Channels with Time-Variant Angles of Arrival
(Chapter; Peer reviewed, 2017)In mobile radio channel modelling, it is generally assumed that the angles of arrival (AOAs) are independent of time. This assumption does in general not agree with real-world channels in which the AOAs vary with the ... -
Utvikling, testing og evaluering av en videobasert læringsressurs for selvstyrt bedriftsopplæring : En casestudie fra Posten Norge AS
(Master thesis, 2017)Opplæring av ansatte er arbeidsgivers plikt og arbeidstakers rett, og er derfor en sentral del ved ethvert arbeidsforhold. Ansattes mulighet for utvikling og innflytelse i egen arbeidssituasjon har også vist seg å være ... -
Experimental Validation for Spectrum Cartography using Adaptive Multi-kernels

On the spectral moments of non-WSSUS mobile-to-mobile double Rayleigh fading channels
(IEEE International Symposium on Personal, Indoor, and Mobile Radio Communications workshops;2017, Journal article; Peer reviewed, 2018)This paper deals with the mathematical analysis of the spectral moments of non-wide-sensestationary uncorrelated-scattering (non-WSSUS) mobile-to-mobile (M2M) double-Rayleigh fading channels. The point of departure is a ... -
Modelling the Doppler Power Spectrum of Non-Stationary Underwater Acoustic Channels Based on Doppler Measurements
(Chapter; Peer reviewed, 2017)This paper proposes a non-stationary time-continuous simulation model for wideband shallow underwater acoustic (UWA) channels based on measured Doppler power spectrums (DPSs). Measurement-based channel simulators are ... -
Consensus-Based Distributed State Estimation of Biofilm in Reverse Osmosis Membranes by WSNs
(Chapter; Peer reviewed, 2017)The appearance of biofilm has become a serious problem in many reverse osmosis based systems such as the ones found in water treatment and desalination plants. In these systems, the use of traditional techniques such as ... -
Topology design to reduce energy consumption of distributed graph filtering in WSN
(Chapter; Peer reviewed, 2017)The large number of nodes forming current sensor networks has made essential to introduce distributed mechanisms in many traditional applications. In the emerging field of graph signal processing, the distributed mechanism ... -
Performance analysis of Alamouti-coded OFDM systems over spatio-temporally correlated underwater acoustic channels
(IEEE International Conference on Communications;2017, Journal article; Peer reviewed, 2017)In this paper, we analyze the performance of Alamouti-coded orthogonal frequency division multiplexing (OFDM) systems over time-varying underwater acoustic (UWA) channels. A realistic UWA channel model has been considered, ... -
