1. 21. Sensor fusion between positioning system and mixed reality

   Master-uppsats, Linköpings universitet/Tekniska fakulteten; Linköpings universitet/Institutionen för datavetenskap

   Författare :Anton Lifwergren; Jonsson Jonatan; [2022]
   Nyckelord :Sensor Fusion; MR; Mixed Reality; AR; Augmented Reality; Positioning; Local Positioning System; Transformation; Mining; Sensorfusion; MR; Mixed Reality; AR; Augmented Reality; Lokalt Positionerings System; Positionering; Transformation; Gruva;

   Sammanfattning : In situations where we want to use mixed reality systems over larger areas, it is necessary for these systems to maintain a correct orientation with respect to the real world. A solution for synchronizing the mixed reality and the real world over time is therefore essential to provide a good user experience. LÄS MER

3. 22. Initial access in 5G mmWave networks with different base station parameters

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

   Nyckelord :Initial Access; Millimeter-Wave Network; Cell Search; Random Search; Genetic Algorithm; Machine Learning; Första åtkomst; Millimetervågsnätverk; Cell sökning; Slumpmässig sökning; Genetisk algoritm; Maskininlärning;

   Sammanfattning : 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). LÄS MER

4. 23. E-Band SPDT RF Switch for a Class F PA in III-V Nanowire MOSFET Technology

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

   Författare :Rungeng Xu; [2022]
   Nyckelord :E-band; III-V Nanowire MOSFET; RF Switch; Class-F PA; Technology and Engineering;

   Sammanfattning : This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. LÄS MER

   Sammanfattning : Abstract Title: “The effect of campaigns on behavioral change” – A Quantitative Investigation of Soft Measures Effect on The Choice of Transportation - Angelika Källström Reduction of the greenhouse gas emission caused from the transport section is one of the world’s biggest challenges. To reduce the greenhouse gas emission researchers has agreed that behavioral change that reduce car use is necessary. LÄS MER

7. 25. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

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

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

   Sammanfattning : 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.
