1. 21. 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

3. 22. An evaluation of LoRa transmission parameter selection for indoor positioning

   University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

   Author : Adina Valjakka; Anton Ahlinder; [2022]
   Keywords : Accuracy; Indoor positioning; LoRa; NLOS; Precision; RSSI; Transmission parameters; Trilateration;

   Abstract : The purpose of this thesis is to investigate how the LoRa modulation configuration affects precision and accuracy when using LoRa for indoor positioning in non-line-of-sight conditions. The aim is to research if an optimum combination of spreading factor, bandwidth, and code rate factor can be found to result in the best possible positioning accuracy and precision, under certain predefined conditions.

4. 23. Spectroscopic model characterisation of hot exoplanet atmospheres

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Author : Elin Sandvik; [2022]
   Keywords : Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

   Abstract : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. READ MORE

5. 24. Indoor 5G Positioning using Multipath Measurements

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Andreas Lidström; Martin Andersson; [2022]
   Keywords : Multipath Propagation; 5G Networks; Target Tracking; Sensor Fusion; Positioning; Particle Filter; Kalman Filter;

   Abstract : Positioning with high precision and reliability is considered as an important feature of new wireless radio networks such as 5G. In areas where satellite positioning is not available or is not reliable enough, 5G can work as an alternative. An example is inside factories where autonomous vehicles might need to be positioned in complex environments. READ MORE

6. 25. Optimal collection grid and transmission line topology for the grid connection of an offshore multi-source park.

   University essay from Uppsala universitet/Elektricitetslära

   Author : Alfred Nerby; [2022]
   Keywords : Renewable; Wind; Solar; multi-source; park; collection grid; substation; transmission; HVAC; HVDC; converters; shunt reactors; transformer; losses; CAPEX; OPEX;

   Abstract : As spacial restrictions become more and more of an issue for renewable energy parks onshore, more developers are turning offshore to develop future production. The desire for a diversity of energy sources combined with a desire to utilize space efficiently has sparked an interest in renewable energy parks where more than one energy source occupy the space.
