  1. 1. Using search based methods for beamforming

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Adam Bergman Karlsson; [2024]
    Nyckelord :Beamforming; Artificial Intelligence; AlphaZero; Radio Resource Management; Monte Carlo Tree Search;

    Sammanfattning : In accommodating the growing global demand for wireless, Multi-User Multiple-Input and Multiple-Output (MU-MIMO) systems have been identified as the key technology. In such systems, a transmitting basestation serves several users simultaneously, increasing the network capacity. LÄS MER

  3. 2. Beamformed Channel Matrix Positioning using 5G Testbench CSI data with a Deep-Learning Pipeline

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

    Författare :Andre Ráth; [2022]
    Nyckelord :5G; Deep Learning; Positioning; Channel State Information; CSI; Deep-learning; neural-network; particle-filter; particle; filter; Channel Matrix; Beamformed Channel Matrix; localization; real-world; data-driven; 5G testbench; basestation; Technology and Engineering;

    Sammanfattning : Within the telecommunications industry, a positioning system for estimating user equipment (UE) location using purely information available for the basestation has an enormous number of potential uses. The link between physical position and the network channel state enables potential positioning systems to function by under- standing the network channel state dependency on location, using a model-based, data-based, or a combined approach.

  4. 3. Analytical Calibration Scheme Suitable for Modern Mobile Communication Systems

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

    Författare :Ramez Hamarneh; [2020]
    Nyckelord :;

    Sammanfattning : Modern systems utilize multiple transceiver modules to enhance capacity by directing the energy of the basestation only at the desired directions using beamforming algorithms. To accurately control the beam patterns, the phase and amplitude at each antenna port must be manipulated to follow the desired beam weight response. LÄS MER

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

    Författare :Adhitya Bharadwaj Sriram; [2018]
    Nyckelord :AAS AdvancedAntennaSystems ; EIRP EquivalentIsotropicRadiatedPower ; mm-Wave MillimeterWave ; ConcealmentMaterials; BaseStation; AAS AdvancedAntennaSystems ; EIRP ekvivalentisotropiskutsråladeffekt ; mm-Wave Millimetervåg ; Maskeringsmaterialen; Radiobasstationer;

    Sammanfattning : With the advent of the 5G technology standard for communication, it is esti-mated that around 50 billion devices around the world will be interconnectedunder this standard [1]. This has prompted the need to investigate new ma-terials, technologies and methods to conceal antennas for preserving the aes-thetic value of urban centers, and preventing these antenna systems from beingidentified or damaged.
