1. 16. 3D Printed Modulated Geodesic Lens Antenna With Even Coverage in the Far-Field

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

   Author : Harald Lindohf; Marcus Wikner; [2022]
   Keywords : 3D-printed; geodesic; modulated; Luneburg; beamforming; lens antenna;

   Abstract : The development of 5G and 6G entails new demandson antennas. This includes fast and reliable connections to a largenumber of devices. A wider area of coverage, and thus moreantennas are also expected, which is problematic for the expensiveantennas used today. To meet those demands, a geodesic lensantenna has been proposed.

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

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Andre Ráth; [2022]
   Keywords : 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;

   Abstract : 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. 18. Fast Clock Synchronization for Large-Scale MEMS Ultrasonic Transducer Arrays

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Karl-Johan Karlsson; [2022]
   Keywords : clock synchronization; clock deskew; MEMS transducer; Delay line; Time-to-Digital conveter;

   Abstract : In many systems today sensors or transmitters need to be read or controlled simultaneously. This thesis investigates a new architecture used for deskewing clock signals between multiple separated parts of a signal transmission system. READ MORE

5. 19. 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

6. 20. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Vinodhini Mylai Chandrasekaran; Nikhila Chinnayanapalli Ravi; [2022]
   Keywords : Antenna Design; mmWave frequency; 5G; FEKO; Technology and Engineering;

   Abstract : The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and many more such applications.
