An adapted eigenvalue-based filter for ocean ambient noise processing
(Peer reviewed; Journal article, 2020)Accurate approximations of Green’s functions retrieved from the correlations of ambient noise require a homogeneous distribution of random and uncorrelated noise sources. In the real world, the existence of highly coherent, ... -
Adaptiv pakketapsbeskyttelse for komprimerte bilder
(Master thesis, 2006)I denne rapporten er det sett på konsekvensene av å benytte UEP(Unequal Error Protection) og EEP(Equal Error Protection) i en skalerbar koder for digital kino. Kompresjonen i digital kino gjøres ved å bruke JPEG2000 del 1 ... -
Adaptive Beamforming Using the Recursive Least Squares Algorithm on an FPGA
(Master thesis, 2015)This thesis describes the design and implementation of a five-channel beamformer using a Space-Time Adaptive Processing (STAP) filter with Recursive Least Squares (RLS) as the adaptive algorithm. The objective of the ... -
Adaptive coded modulation : design and simulation with realistic channel state information
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:38, Doctoral thesis, 2005)Spectrally efficient transmission schemes are becoming a more common requirement for digital communication systems. Especially in wireless communication since the bandwidth of available frequencies is a shared resource. ... -
Adaptive coded modulation in spatial and multiuser diversity systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:49, Doctoral thesis, 2005)This thesis consists of five included papers plus an introduction. The majority of the papers are devoted to performance analysis of an adaptive coded modulation (ACM) scheme based on multidimensional trellis codes. ... -
Adaptive Coded Modulation Performance and Channel Estimation Tools for Flat Fading Channels
(Dr. ingeniøravhandling, 0809-103X; 2002:18, Doctoral thesis, 2002)The need for spectrally efficient transmission on mobile and wireless channels is prevalent. A promising scheme for such transmission is adaptive coded modulation. In this thesis, techniques for assessing the performance ... -
Adaptive Coding and Modulation Techniques for HF Communication: Performance of different adaption techniques implemented with the HDL+ protocol
(Master thesis, 2009)The main goal of this thesis is to present two good alternatives for the HDL+ protocol proposed for ratification in STANAG 4538, as this partially is restricted by a patent claims. The HDL+ protocol is used as a starting ... -
Adaptive Frequency Hopping with Channel Prediction
(Master thesis, 2006)The number of radio systems operating in the 2.4 GHz band is rising as a result of increased usage of wireless technologies. Since such devices interfere with one another, satisfactory co-existence becomes important. Several ... -

Adaptive Graph Filters in Reproducing Kernel Hilbert Spaces: Design and Performance Analysis
(Peer reviewed; Journal article, 2021)This paper develops adaptive graph filters that operate in reproducing kernel Hilbert spaces. We consider both centralized and fully distributed implementations. We first define nonlinear graph filters that operate on ... -
Adaptive non-parametric methods of time-frequency analysis applied on marine propulsion systems
(Master thesis, 2015)Time-Frequency analysis is an invaluable tool for Rolls-Royce Marine as it helps scheduling maintenance when it is actually needed, rather than periodical appointments. A docked ship means reduced income so avoiding ... -
Adaptive Store and Forward - A look into possible solutions for the increasing resource consumption in wireless sensor networks
(Master thesis, 2016)Over the recent years the interest for wireless sensor networks and Internet of Things (IoT) has grown significantly. As a consequence of this, there is a need for solutions to conserve restricted resources such as energy ... -
Addressing Challenges in Fabricating Reflection-2 Based Fiber Optic Interferometers
(Journal article; Peer reviewed, 2019)abrication of multimode fiber optic interferometers requires accurate control of certain parameters to obtain reproducible results. This paper evaluates the consequences of practical challenges in fabricating reflection-based, ... -
Addressing the Sustainable Development Goals with a System-of-Systems for Monitoring Arctic Coastal Regions
(Peer reviewed; Journal article, 2020)Norway has a large coastal industry and a strong motivation for developing systems to enable sustainable management of ocean resources. Recent advances in collaborating autonomous systems, Internet-of-Things, microsatellites, ... -
Adjusting FEC for Real-Time Video Communication Using Reinforcement Learning
