  1. 11. Initial access in 5G mmWave networks with different base station parameters

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

    Author : Xiao Yang; [2022]
    Keywords : Initial Access; Millimeter-Wave Network; Cell Search; Random Search; Genetic Algorithm; Machine Learning; Första åtkomst; Millimetervågsnätverk; Cell sökning; Slumpmässig sökning; Genetisk algoritm; Maskininlärning;

    Abstract : Nowadays in the fifth generation (5G) communication systems, millimeter wave (mmWave) has aroused interest to not only industrial use but also network operators due to the massive amount of bandwidth available at mmWave frequencies. Initial access in cellular systems is an essential procedure in which new mobile user equipment (UE) establishes a connection with a base station (BS). READ MORE

  3. 12. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    University essay from KTH/Tillämpad fysik

    Author : Marie Defives; [2022]
    Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

  4. 13. Low-profile fully-metallic Luneburg lens antenna

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

    Author : Justine Djounidi; [2022]
    Keywords : Beam Scanning; Luneburg Lens Antenna; Fully-metallic; Millimeter Wave; Vinkelskanning; Luneburg Linsantenn; Fullt Metalliskt; Millimetervåg;

    Abstract : Modern communication systems face new technological challenges, such as the narrowness and overload of the conventional frequency bands employed for these applications. Nowadays, communication systems are expected to operate at higher frequencies, such as the mm-wave band. READ MORE

  5. 14. Raytracing in Channel Model Development

    University essay from Karlstads universitet

    Author : Andreas Rogne; [2022]
    Keywords : ;

    Abstract : The fifth generation of mobile internet is upon us, but still, there is work to do before the new technology is fully utilized. The new generation of cellular network promises frequencies ranging from the sub – 6 GHz to 39 GHz, the latter being in the mmWave spectrum. READ MORE
