    Sammanfattning : This thesis is based on nine papers, all concerned with parameter estimation. The thesis aims at solving problems related to real-world applications such as spectroscopy, DNA sequencing, and audio processing, using sparse modeling heuristics. LÄS MER

  3. 3. Fiber-based all-optical sampling for ultrafast waveform monitoring

    Detta är en avhandling från Mathematical Statistics, Centre for Mathematical Sciences, Lund University

    Författare :Mathias Westlund; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization independent; waveform monitoring; software synchronization; four-wave mixing; all-optical sampling;

    Sammanfattning : Digital sampling is a technique to visualize a time-varying waveform by capturing quasi-instantaneous snapshots of a signal via a sampling gate. The gate is opened and closed by narrow pulses in a pulse train having a well defined repetitive behaviour such that all parts of the waveform are measured. LÄS MER

  4. 4. Identification of Stochastic Continuous-time Systems : Algorithms, Irregular Sampling and Cramér-Rao Bounds

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Larsson; Uppsala universitet.; Uppsala universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Sammanfattning : The problem of identifying continuous-time systems is of fundamental interest in various areas, such as astrophysics, economics, control and signal processing. The most obvious reason for working with continuous-time models is that most physical systems are inherently continuous in time. LÄS MER

  5. 5. Ultra Wideband: Communication and Localization

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Vijaya Parampalli Yajnanarayana; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra Wideband; TOA; Kalman Filter; Localization; Physical Layer Signaling; Location Aware Communication; Compressive Sampling; Sparse Signal Processing; Wireless Sensor Network; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The first part of this thesis develops methods for UWB communication. To meet the stringent regulatory body constraints, the physical layer signaling technique of the UWB transceiver should be optimally designed. LÄS MER
