1. Increasing energy efficiency of O-RAN through utilization of xApps
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : 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.

2. Digital Front End Algorithms for Sub-Band Full Duplex
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

3. Integrated Sensing and Communicationusing OFDM and Stepped FMCWSignals : Proof-of-Concept and Evaluation with Software DefinedRadios
Master-uppsats, Blekinge Tekniska Högskola/Fakulteten för datavetenskaperSammanfattning : The thesis work shows the implementation of sensing and communication, so a basic knowledge of analog and digital communication systems is needed to understand this paper Background. With the increase in smart devices, the bandwidth requirements are increased, which created congestion in the radio spectrum resources. LÄS MER
4. Investigation of Antenna Radomes in Low Earth Orbits
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : 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.

5. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
