  3. 2. Characterization and Correction of Analog-to-Digital Converters

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

    Sammanfattning : 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. LÄS MER

  4. 3. Multidimensional Constellation Shaping for Coherent Optical Communication Systems

    Författare :Ali Mirani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lattice-based constellations; geometric shaping; probabilistic shaping; multidimensional modulation format; Voronoi constellation; constellation shaping; optical communications; coherent receiver;

    Sammanfattning : To overcome the increasing demands for Internet traffic, exploiting the available degrees of freedom in optical communication systems is necessary. In this thesis, we study how constellation shaping can be achieved in various dimensions and how various shaping schemes affect the whole performance in real systems. LÄS MER

  5. 4. Parameter Estimation and Waveform Fitting for Narrowband Signals

    Författare :Tomas Andersson; Peter Händel; István Kollár; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : Frequency estimation has been studied for a large number of years. One reason for this is that the problem is easy to understand, but difficult to solve. Another reason, for sure, is the large number of applications that involve frequency estimation, e. LÄS MER

  7. 5. Control of Hybrid Electric Vehicles with Diesel Engines

    Författare :Karin Jonasson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; simulation; hybrid vehicle; diesel engines; Automation; control engineering; robotics; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). LÄS MER
