  1. 1. Estimation-based iterative learning control

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Jian-Xin Xu; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iterative learning control; estimation; industrial robotics; performance; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Sammanfattning : In many  applications industrial robots perform the same motion  repeatedly. One way of compensating the repetitive part of the error  is by using iterative learning control (ILC). The ILC algorithm  makes use of the measured errors and iteratively calculates a  correction signal that is applied to the system. LÄS MER

  4. 4. Channel Estimation and Self-Interference Suppression for MIMO Relaying Systems

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Panagiota Lioliou; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation; expectation-maximization EM ; half-duplex; Bayesian; multiple-input multiple-output MIMO ; Cramer-Rao Bound CRB ; full-duplex; relays; performance analysis; Kalman filter KF ; self-interference.; Amplify-and-forward AF ; least squares LS ;

    Sammanfattning : Recently, the introduction of relaying nodes in wireless channels has been identified as a promising technique for providing broader coverage, higher transmission rates, and increased reliability. Moreover, when the concept of relaying systems is combined with that of multiple-input multiple-output (MIMO) technology, thesystem performance can be further improved by exploiting the spatial dimension.
