  1. 11. Multipath Packet Scheduling for 5G Systems

    Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Författare :Jonas Hammar; [2022]
    Nyckelord :MPTCP; 5G; scheduling; path asymmetry; Mininet;

    Sammanfattning : Modern mobile phones often have multiple network interfaces. By utilising these interfaces concurrently, the user experience can be enhanced, e.g., increased performance, stability and reliability. LÄS MER

  3. 12. Characterisation and Modeling of RF environment

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Patric Beas Petersson; [2022]
    Nyckelord :signal processing; passive radar; antenna array; data processing; signalbehandling; passiv radar; antennarray; databehandling;

    Sammanfattning : Devices that transmit and receive electromagnetic signals are today central to the way people communicate and acquire information from the surroundings. WiDAR, Wideband Digital Array Receiver, is the name of a new system of digital antenna array receivers, which has recently been developed at Saab in Järfälla and is the focus of this thesis. LÄS MER

  4. 13. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Felix Gustafsson; [2022]
    Nyckelord :Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Sammanfattning : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

  5. 14. Indoor 5G Positioning using Multipath Measurements

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Andreas Lidström; Martin Andersson; [2022]
    Nyckelord :Multipath Propagation; 5G Networks; Target Tracking; Sensor Fusion; Positioning; Particle Filter; Kalman Filter;

    Sammanfattning : Positioning with high precision and reliability is considered as an important feature of new wireless radio networks such as 5G. In areas where satellite positioning is not available or is not reliable enough, 5G can work as an alternative. An example is inside factories where autonomous vehicles might need to be positioned in complex environments. LÄS MER

  7. 15. ML-Aided Cross-Band Channel Prediction in MIMO Systems

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Alejo Pérez Gómez; [2022]
    Nyckelord :MIMO; Deep Learning; Machine Learning; Probabilistic Principal Component Analysis; Variational Autoencoder;

    Sammanfattning : Wireless communications technologies have experienced an exponential development during the last decades. 5G is a prominent exponent whose one of its crucial component is the Massive MIMO technology. LÄS MER
