1. 1. Personalized Federated Learning for mmWave Beam Prediction Using Non-IID Sub-6 GHz Channels

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

   Author : Yuan Cheng; [2022]
   Keywords : Personalized Federated Learning; Millimeter wave; Beamforming; DeepMIMO; Non-IID; Personaliserad Federad Inlärning; Millimetervågor; Strålformning; DeepMIMO; Icke-IID;

   Abstract : While it is difficult for base stations to estimate the millimeter wave (mmWave) channels and find the optimal mmWave beam for user equipments (UEs) quickly, the sub-6 GHz channels which are usually easier to obtain and more robust to blockages could be used to reduce the time before initial access and enhance the reliability of mmWave communication. Considering that the channel information is collected by a massive number of radio base stations and would be sensitive to privacy and security, Federated Learning (FL) is a match for this use case.

3. 2. Cross coupling in a two-axis control system for stabilized platforms

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

   Author : Bill Lavebratt; [2022]
   Keywords : MIMO; Modeling; Two-axis gimbal system; Decoupler; Inner loop disturbance compensation; Control theory.;

   Abstract : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. READ MORE

4. 3. Adaptive Modulation Coding Scheme in Amplify and Forward Relay Networks

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Nirnay Reddy Nallavelli; Sushma Swaraj Chilupuri; [2022]
   Keywords : Adaptive Modulation; Modulation and Coding Schemes; Amplify and Forward; Signal to Noise Ratio; Nakagami-m Distribution.;

   Abstract : Wireless communications have become an essential part of our daily life. Despite the fact that wireless networks are simple to set up and deploy, the channel conditionsin wireless networks are susceptible to fading and attenuation, thereby reducing the transmission efficiency and reliability.

5. 4. Decomposing the Consumption Response to Monetary Policy Shocks in Australia

   University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Author : Jessica Geraghty; [2022]
   Keywords : Consumption; Household heterogeneity; Income distribution; Marginal propensity to consume; Monetary policy transmission;

   Abstract : Does monetary policy affect households differently depending on their position on the income distribution? If so, what drives the differences? This paper attempts to answer these questions by decomposing changes in consumption following a monetary policy shock into several direct and indirect channels of transmission. Although direct channels of transmission are the most important in traditional representative agent models, the indirect channels are dominant when households are heterogeneous. READ MORE

6. 5. Digitizing and Mapping Channel Heads Across Various Forested Regions in Sweden Using a High-Resolution DEM : A Regional Analysis of How Landscape Properties Influencing Channel Head Initiation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Amanda Jarefjäll; [2021]
   Keywords : ;

   Abstract : Acting as a hydrological link between the terrestrial landscape and the larger downstream river network, channel heads and their immediate headwaters are essential geomorphological features in our landscape. Not only due to their ability to transport water and sediment and cycling of nutrients, but as an important component for ecosystem productivity and aquatic habitats. READ MORE
