1. 31. Overcoming Inter-carrier-interference in OFDM System

   Magister-uppsats, Linköpings universitet/Kommunikationssystem

   Författare :Fukang Guo; Luoan Lu; [2021]
   Nyckelord :ICI; OFDM; TDCP; FDCE; Windowing-OFDM; 5G;

   Sammanfattning : This master thesis aims for Inter-carrier interference (ICI) mitigation in orthogonal frequency division multiplexing (OFDM) system by considering designs of frequency domain cyclic extension(FDCE) and optimal windowing pulse shape. Although OFDM system has been put forward in the 1970s, it has just emerged in 4G. LÄS MER

3. 32. Machine Learning Technique for Beam Management in 5G NR RAN at mmWave Frequencies

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

   Författare :Joel Bill; Gustav Fahlén; [2020]
   Nyckelord :Machine Learning; Reinforcement Learning; Beam Management; Beam Tracking; mmWaves; Technology and Engineering;

   Sammanfattning : Ericsson has an interest in investigating if the fast-growing concept known as machine learning can be applied to beam management, in a 5G NR environment using mmWave frequencies. Because of the high path-loss at mmWave frequencies and high throughput demands of 5G NR systems it is crucial to the UE to always stay connected to the most suitable beam, to provide highest possible throughput.

   Nyckelord :5G; 4G; Stream test;

   Sammanfattning : In this day and age, with highly available and fast networks, many tasks are being performed remotely. However, certain tasks cannot be flawlessly executed remotely, for instance, the tasks performed by professional drivers. LÄS MER

5. 34. Communication Channel Analysis for Efficient Beamforming

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Författare :Manoj Sai Manda; [2020]
   Nyckelord :Communication Channel; Beamforming; MIMO; Signal processing;

   Sammanfattning : In this modern communication era, we are surrounded by unlimited electronic devices, the need to connect with everyone and everything increases dramatically. As the number of electronic devices increases, the amount of data to process increases and the need for higher data speeds occurs. LÄS MER

7. 35. QUIC Behavior over Dual Connectivity : Understanding QUIC throughput and fairness

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :David Hasselquist; Christoffer Lindström; [2020]
   Nyckelord :QUIC; Dual Connectivity; Throughput; Fairness;

   Sammanfattning : QUIC is a relatively new transport layer network protocol that has gained popularity over the last few years. The protocol was initially developed by Google and standardization work has been continued by the Internet Engineering Task Force (IETF) with the goal of it becoming the next generation transport protocol.
