  1. 1. Increasing energy efficiency of O-RAN through utilization of xApps

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Fredrik Borg; [2023]
    Keywords : telecom; o-ran; ric; xapp; radio access networks; energy efficiency;

    Abstract : As 5G becomes more established and faces widespread roll-out, energy consumption of radio access networks around the globe will increase. Since the high-frequency radio waves used in 5G communication has a shorter effective range compared to the waves used in previous generations, 5G networks will require a higher number of radio units to compensate for their reduced range.

  3. 2. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  4. 3. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Olle Sundberg; Vincent Forsberg; [2023]
    Keywords : ;

    Abstract : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. READ MORE

  5. 4. Arbitrary motion Synthetic Aperture Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Alberius; Erik Rolander; [2023]
    Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

  6. 5. Trace Visualization of Distributed and Centralized Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
