1. 1. Channel Estimation Optimization in 5G New Radio using Convolutional Neural Networks

   University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Author : David Adolfsson; [2023]
   Keywords : Channel Estimation; 5G NR; CNN; Kanalestimering; 5G NR;

   Abstract : Channel estimation is the process of understanding and analyzing the wireless communication channel's properties. It helps optimize data transmission by providing essential information for adjusting encoding and decoding parameters. READ MORE

3. 2. Performance Analysis of STTC-Based MIMO Under Cognitive RadioScenarios

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Sanjana Kankantee; Sai Praneeth Reddy Ganta; [2023]
   Keywords : Space-time trellis coding; MIMO; Cognitive radio; Performance; Bit error rate; Diversity; AWGN; Rayleigh fading; Detection; Spectrum.;

   Abstract : This thesis presents a comprehensive investigation into improving wireless transmission rates and reliability through the implementation of Space Time Trellis Codes(STTC). The study focuses on enhancing the coding gain, diversity gain, and flexible transmission capabilities, which are crucial for Error-Correcting Codes (ECC)in wireless communications. READ MORE

4. 3. Diffusion-Based MR Methods for Measuring Water Exchange

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Shan Cai; [2022]
   Keywords : diffusion MRI; water exchange rate; membrane permeability; double diffusion encoding; DDE;

   Abstract : Measuring transmembrane water exchange can provide potential biomarkers for tumors and brain disorders. Diffusion Magnetic Resonance Imaging (dMRI) is a well-established tool that can non-invasively measure water exchange across cell membranes. Diffusion Exchange Spectroscopy (DEXSY) is one of the dMRI-based frameworks used to estimate exchange. READ MORE

5. 4. Evaluating performance of homomorphic encryption applied on delta encoding

   University essay from Linköpings universitet/Databas och informationsteknik

   Author : János Richard Dani; [2022]
   Keywords : homomorphic encryption; delta encoding; performance test;

   Abstract : Homomorphic encryption is an encryption scheme that allows for simple operations on encrypted data. These operations are mainly boolean circuits combined into more complexarithmetic operations, rotations, and others. Homomorphic encryption was first implemented in 2009, and in the following decade, many different versions emerged. READ MORE

6. 5. Evaluation of Scheduling Policies for XR Applications

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

   Author : Neelabhro Roy; [2022]
   Keywords : Extended Reality; Virtual Reality; Edge Computing; Resource allocation; Scheduling policies; Multi-layered video encoding; online scheduling; maximum-bipartite weighted matching; competitive analysis; Extended Reality; Virtual Reality; Edge Computing; Resursallokering; Schemaläggningspolicyer; Flerskiktig videokodning; onlineschemaläggning; maximalt tvådelad viktad matchning; konkurrensanalys;

   Abstract : Immersion based technologies such as Augmented Reality (AR), Virtual Reality (VR) and Mixed Reality (MR), together falling under the umbrella of Extended Reality (XR) have taken the world by storm in the recent past. However, with the growing market and the increasing number of applications of XR, multiple challenges have arisen. READ MORE
