  1. 1. Adaptive Multidimensional Filtering

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Leif Haglund; Gösta Granlund; [1991]

    Sammanfattning : This thesis contains a presentation and an analysis of adaptive filtering strategies for multidimensional data. The size, shape and orientation of the flter are signal controlled and thus adapted locally to each neighbourhood according to a predefined model. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Filter Bank Design; Subband Adaptive Filtering;

    Sammanfattning : Adaptive filtering is an important subject in the field of signal processing and has numerous applications in fields such as speech processing and communications. Examples in speech processing include speech enhancement, echo- and interference- cancellation, and speech coding. LÄS MER

  3. 3. Optimal and Adaptive Subband Beamforming

    Detta är en avhandling från Ronneby : Blekinge Institute of Technology

    Författare :Nedelko Grbic; ; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Optimal; Adaptive; Speech Enhancement;

    Sammanfattning : The increased use of personal communication devices, personal computers and wireless cellular telephones enables the development of new inter-personal communication systems. The merge between computers and telephony technologies brings up the demand for convenient hands-free communications. LÄS MER

  4. 4. Adaptive spatial filtering of fMRI data

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Joakim Rydell; [2005]

    Sammanfattning : Functional magnetic resonance imaging (tMRI) is a method for detecting brain regions that are activated when a certain task is carried out. The method is useful in planning of neurosurgical procedures, where knowledge of the exact locations of important functions is needed to avoid damage to these regions. LÄS MER

  5. 5. Data Filtering and Control Design for Mobile Robots

    Detta är en avhandling från Stockholm : KTH

    Författare :Maja Karasalo; Xiaoming Hu; John Baras; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; formation control; tracking; nonlinear control; optimal smoothing; adaptive filtering; MATHEMATICS Applied mathematics Optimization; systems theory; MATEMATIK Tillämpad matematik Optimeringslära; systemteori;

    Sammanfattning : In this thesis, we consider problems connected to navigation and tracking for autonomousrobots under the assumption of constraints on sensors and kinematics. We study formation controlas well as techniques for filtering and smoothing of noise contaminated input. The scientific contributions of the thesis comprise five papers. LÄS MER
