1. 16. Machine Learning Based Beam Tracking in mmWave Systems

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

   Author : Yizhan Yang; [2021]
   Keywords : Beam Tracking; Machine Learning; RNN; LSTM; Strålspårning; Maskininlärning; RNN; LSTM;

   Abstract : The demand for high data rates communication and scarcity of spectrum in existing microwave bands has been the key aspect in 5G. To fulfill these demands, the millimeter wave (mmWave) with large bandwidths has been proposed to enhance the efficiency and the stability of the 5G network. READ MORE

3. 17. Adaptive Beam Management in 5G-NR: A Machine Learning Perspective

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

   Author : Boqiang Wang; [2021]
   Keywords : Machine Learning; Neural Network; Beam Management; Beam Tracking; mmWaves; 5G NR; Beamforming; Technology and Engineering;

   Abstract : In this rapid era of technology, speed of communication has become an important factor. To overcome this challenge, 5G/NR technology is being explored. One of the ways of doing this is by using the so called millimeter wave spectrum. READ MORE

4. 18. POPULISM AND POLITICIZATION OF THE BUREACRACY An empirical analysis of the effect of populist rule in Europe and Latin America

   University essay from Göteborgs universitet/Statsvetenskapliga institutionen

   Author : Martin Hammarén; [2020-07-03]
   Keywords : populism; bureaucracy; politicization;

   Abstract : Do populist rule lead to more politicization? As populists have had electoral success in many countries in recent years, populism has received much attention both in the public debate an in political science. One aspect of the concept, how populists act once in power and how they relate to the state bureaucracy has however, so far, received only little attention. READ MORE

5. 19. Implementation of Spectrum Analysis Functionality for IQ-Signal.

   University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Author : Gedion Biredaw Anbessa; [2020]
   Keywords : RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

   Abstract : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).

6. 20. Machine Learning Technique for Beam Management in 5G NR RAN at mmWave Frequencies

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

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

   Abstract : 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.
