1. 16. Simulation of Radio Propagation Path in Indoor Environment

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

   Author : Minu Revathikumar; [2022]
   Keywords : Indoor 3D propagation model; millimeter waves mmWaves ; 5G; Basic propagation mechanism; Excess loss; Inomhus 3Dspridnings modell; millimeter vågor mmVågor ; 5G; Grundläggande spridnings mekanism; Överskotts förlust;

   Abstract : Several propagation channel models are designed to verify signal behavior in specific environments for future 5G cellular networks. Hence, with the massive development and demand of indoor wireless systems, a suitable design prior to deployment is required for energy and cost-efficient implementations. READ MORE

3. 17. Sensor fusion between positioning system and mixed reality

   University essay from Linköpings universitet/Tekniska fakulteten; Linköpings universitet/Institutionen för datavetenskap

   Author : Anton Lifwergren; Jonsson Jonatan; [2022]
   Keywords : 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;

   Abstract : 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. READ MORE

4. 18. 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

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

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

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

   Abstract : 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. 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.
