  1. 11. On Detection and Estimation of Multiple Sources in Radar Array Processing

    Författare :Jonny Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatially correlated noise; Cramer-Rao bounds; estimation; feature reduction; virtual uniform linear arrays; classification; adaptive data reduction; nonlinear weighted least squares; multiple targets; detection;

    Sammanfattning : This thesis deals with detection and estimation problems in sensor array signal processing. We treat the multiple hypothesis problem for complex sinusoids observed in spatially colored noise. LÄS MER

  3. 12. Tuning of Anomaly Detectors in the Presence of Sensor Attacks

    Författare :David Umsonst; Henrik Sandberg; Justin Ruths; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Critical infrastructures, such as the power grid and water distribution networks, are the backbone of our modern society. With the integration of computational devices and communication networks in critical infrastructures, they have become more efficient, but also more vulnerable to cyberattacks. LÄS MER

  4. 13. Towards conformal methods for large-scale monitoring of district heating substations

    Författare :Shiraz Farouq; Stefan Byttner; Mohamed-Rafik Bouguelia; Henrik Gadd; Harris Papadopoulos; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Increasing technical complexity, design variations, and customization options of IoT units create difficulties for the construction of monitoring infrastructure. These units can be associated with different domains, such as a fleet of vehicles in the mobility domain and a fleet of heat-pumps in the heating domain. LÄS MER

  5. 14. Wireless Communication Networks for Time-critical Industrial Applications

    Författare :Xiaolin Jiang; Carlo Fischione; Nikolaj Marchenko; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Sammanfattning : Wireless communication is of paramount importance to enable the vision of Industry 4.0. Compared to mobile communications, industrial communications pose demanding requirements in terms of ultra low latency and high reliability. LÄS MER

  7. 15. Interference Rejection and Channel Detection in Mobile Communication

    Författare :Fredrik Nordström; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; detection of abrupt changes; WCDMA; Viterbi decoder; Kalman filter; co-channel interference; TDMA; EDGE; Mathematics; Matematik;

    Sammanfattning : This thesis is devoted to statistical problems in mobile communication, in particular disturbance rejection and change detection are studied. Co-channel interference is a significant problem for systems based on TDMA, e.g. EDGE. LÄS MER
