1. 21. Nonlinear effects and predictions in advanced antenna systems in 5G Distortion Effects in 5G

   University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

   Author : Altahra Mohammed; [2019]
   Keywords : PA; DPD; Active load-pull; Calibration.;

   Abstract : In the next-generation wireless cellular communication systems known as 5G, radio equipment will be deployed in several frequency bands, among them is the millimeter wave bands (26 - 40 GHz). The use of these high frequencies can help to mitigate the limited spectrum problem and higher data rates can be achieved [2] . READ MORE

4. 23. Channel Reconstruction for High-Rank User Equipment

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

   Author : Yu Zhao; [2019]
   Keywords : Deep learning; 5G; massive MIMO; Channel reconstruction; Telecommunication; Artificial Intelligence; Djup lärning; 5G; massiv MIMO; Kanalrekonstruktion; Telekommunikation; Artificiell intelligens;

   Abstract : In a 5 Generation massive Multiple Input Multiple Output radio network, the Channel State Information is playing a central role in the algorithm design and system evaluation. However, Acquisition of Channel State Information consumes system resources (e.g. time, frequency) which in turn decrease the link utilization, i. READ MORE

5. 24. Analysis and Compensationfor Clipping-like Distortion of the Transmitted Signal in Massive MIMO Systems

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Adel Fayad; [2018]
   Keywords : Master; Thesis; Massive MIMO; Clipping; Distortion; Power amplifier distortion; SNR; Error Probability;

   Abstract : This project consists of analyzing and finding solutions to the effect of non-linear distortionon the performance of a Massive Multiple Input Multiple Output (MIMO) system interms of Spectral Efficiency (SE) and Symbol Error Rate (SER). Massive MIMO is one ofthe technologies that are considered the backbone of the 5th generation of wireless communicationsand therefore this technology has gathered much interest from researchersand companies alike [19], as it is proven that this kind of system greatly improves thecapacity of the wireless connection [8].

6. 25. Estimation of Statistical Properties in a Mobile MIMO System

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

   Author : Torsten Molitor; Hilding Wollbo; [2018]
   Keywords : ;

   Abstract : Several measures to evaluate the stationarity of a MIMO radio channel are proposed and implemented. The analysis is performed on a Kronecker model implementation of the channel matrix covariance, which describes the statistical characteristics and transmission properties of the radio channel.
