  2. 1. Exploiting Prior Information in Parametric Estimation Problems for Multi-Channel Signal Processing Applications

    Author : Petter Wirfält; Magnus Jansson; Abdelhak Zoubir; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Array signal processing; covariance matrix; damped sinusoids; direction of arrival estimation; frequency estimation; Kronecker; NQR; NMR; parameter estimation; persymmetric; signal processing algorithms; structured covariance estimation; Toeplitz; Array; signalbehandling; kovariansmatris; dämpad sinus; riktningbestämning; frekvensskattning; Kronecker; NQR; NMR; parameterestimering; persymmetrisk; algoritm; strukturerad kovariansmatris; Toeplitz;

    Abstract : This thesis addresses a number of problems all related to parameter estimation in sensor array processing. The unifying theme is that some of these parameters are known before the measurements are acquired. READ MORE

  4. 2. Classification and Localization of Vehicle Occupants Using 3D Range Images

    Author : Pandu Ranga Rao Devarakota; Bjorn Ottersten; Hamid Krim; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Abstract : This thesis deals with the problem of classifying automotive vehicle occupants and estimating their position. This information is critical in designing future smart airbag systems providing maximum protection for passengers. READ MORE

  5. 3. Interference Mitigation and Synchronization for Satellite Communications

    Author : Joel Grotz; Björn Ottersten; Dirk Slock; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Abstract :  Within this thesis, the satellite broadcast scenario of geostationary satellites is reviewed. The densely crowded geostationary arc in the common broadcast frequencies may create significant interference from adjacent satellites (ASI). READ MORE

  6. 4. Antenna array mapping for DOA estimation in radio signal reconnaissance

    Author : Per Hyberg; Björn Ottersten; Alex Gershman; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Array mapping; array interpolation; Signalbehandling; Signal processing; Signalbehandling;

    Abstract : To counter radio signal reconnaissance, an efficient way of covert communication is to use subsecond duration burst transmissions in the congested HF band. Against this background, the present thesis treats fast direction finding (DF) using antenna arrays with known response only in a few calibration directions. READ MORE

  7. 5. Characterization and Correction of Analog-to-Digital Converters

    Author : Henrik Lundin; Peter Händel; Mikael Skoglund; Paolo Carbone; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital converter; ADC; correction; post-correction; look-up table; characterization; calibration; Signal processing; Signalbehandling;

    Abstract : Denna avhandling behandlar analog-digitalomvandling. I synnerhet behandlas postkorrektion av analog-digitalomvandlare (A/D-omvandlare). A/D-omvandlare är i praktiken behäftade med vissa fel som i sin tur ger upphov till distorsion i omvandlarens utsignal. READ MORE
