  1. 31. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Johan Kövamees; [2020]
    Nyckelord :Electrically Steerable Phased-Arrays for 5G Sub-6 GHz Massive MIMO Active Antenna Units;

    Sammanfattning : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. LÄS MER

  3. 32. Test setup for LDMX HCal readout

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Joshua Greaves; [2020]
    Nyckelord :Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Sammanfattning : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  4. 33. Communication Channel Analysis for Efficient Beamforming

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Manoj Sai Manda; [2020]
    Nyckelord :Communication Channel; Beamforming; MIMO; Signal processing;

    Sammanfattning : In this modern communication era, we are surrounded by unlimited electronic devices, the need to connect with everyone and everything increases dramatically. As the number of electronic devices increases, the amount of data to process increases and the need for higher data speeds occurs. LÄS MER

  5. 34. Investigation on Positioning Techniques for Indoor Office Scenario

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Yan Shu; Yujie Zhang; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master thesis aims to investigate downlink positioning techniques and improve fifth-generation (5G) cellular positioning performance in the indoor office scenario. In the thesis work, we target in the indoor office scenario because it is a typical deployment scenario standardized in 3GPP release 16. LÄS MER

  7. 35. High Magnetic Field in Low Temperature Vacuum Conditions : Magnet Design, Modeling and Testing

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Nehir Schmid; [2020]
    Nyckelord :magnet; pulsed magnet; X-ray diffraction; crystallography; zylon; magnet design; magnetic field; high magnetic field; strong magnetic field; split-coil magnet;

    Sammanfattning : The Swiss Free Electron Laser (SwissFEL) at the Paul Scherrer Institute is a national prestige project that will enable ground breaking new x-ray scattering experiments in areas such as biology, chemistry and physics. A plannedactivity is to generate possibility for x-ray diffraction under high pulsed magnetic fields to explore quantum mattermaterials. LÄS MER
