  1. 1. FPGA Implementation of an Online Free-Space Optical Communications Test-Bed

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hamza Mahmoud; [2023]
    Nyckelord :Test-bed; FPGA design; PRBS; FSO; Optical communication; Testbädd; FPGA-design; PRBS; FSO; Optisk kommunikation;

    Sammanfattning : Free Space Optical (FSO) satellite communications is proving to be a key enabling technology for global connectivity with the ability to provide connection across Europe with only 12 ground stations. For this, Deutsches Zentrum für Luft- und Raumfahrt (DLR) is working on implementing a robust communication system for FSO on a Xilinx RFSoC Field Programmable Gate Array (FPGA)( ZU28DR). LÄS MER

  3. 2. Deep Learning for Predicting Electrical Power in 5G

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Robert Mellberg; [2022]
    Nyckelord :5G; Deep learning; Machine learning; Predictions; Electrical power; 5G; Djupinlärning; Maskininlärning; Förutsägelser; Elektrisk effekt;

    Sammanfattning : 5G is currently being implemented around the world. A way to save resources in 5G could be to have several sector carriers sharing one power source. This requires being able to predict the electrical power of the sector carriers to make sure they do not exceed the capability of the power source. LÄS MER

  4. 3. Optimization of Physical Uplink Resource Allocation in 5G Cellular Network using Monte Carlo Tree Search

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gerard Girame Rizzo; [2022]
    Nyckelord :5G NR; PUCCH format; Combinatorial optimization; Physical resource allocation; Monte Carlo Tree Search; 5G NR; PUCCH-format; kombinatorisk optimering; fysisk resursfördelning; Monte Carlo Tree Search;

    Sammanfattning : The Physical Uplink Control Channel (PUCCH), which is mainly used to transmit Uplink Control Information (UCI), is a key component to enable the 5G NR system. Compared to LTE, NR specifies a more flexible PUCCH structure to support various applications and use cases. LÄS MER

  5. 4. Enhancements of Positioning for IoT Devices

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

    Författare :Hatem Odetalla; Guoda Tian; [2018]
    Nyckelord :Internet of Things; IoT; NB-IoT; Narrowband IoT; Positioning; OTDOA; PRS; Positioning Reference Signal; Technology and Engineering;

    Sammanfattning : The aim of this thesis work is to find novel method(s), which enhance the performance of the existing Observed Time Difference of Arrival (OTDOA) positioning technique for Internet of Thing (IoT) devices introduced in Third Generation Partnership Project (3GPP) standard release 14. In this thesis work, NarrowBand IoT (NB-IoT) positioning is considered as the baseline. LÄS MER

  7. 5. Development of an FPGA-based High-Speed Wireless Communication System in the 60GHz Frequency Band For CERN facilities and 5G deployment

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Mohamed Jaoua; [2018]
    Nyckelord :;

    Sammanfattning : The work is devoted in the development and the exploration of the capabilities of the state of art unlicensed 60GHz (V-Band) mm-wave band that has raised so much interest and attention from numerous companies and laboratories for implementing Multi-gigabit communications [17] and especially for the 5th generation of cellular network and wireless systems. Implementing a high wireless data transfer system requires a high bandwidth and the one around the 60GHz frequency turned out to be a very promising candidate [13]. LÄS MER
