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

    Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :David Adolfsson; [2023]
    Nyckelord :Channel Estimation; 5G NR; CNN; Kanalestimering; 5G NR;

    Sammanfattning : 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. LÄS MER

  3. 2. Extension of an Existing Simulator for Cellular Communication with Support for 5G NR : Porting of MIMO Channel Estimation Methods form a prototype to an existing Link-Level Simulator

    M1-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Författare :Majed Haj Hussein; Abdulsalam Alnahawi; [2022]
    Nyckelord :5G NR; Channel Estimation; MIMO; OFDM; DMRS;

    Sammanfattning : Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are two efficient technologies used to achieve higher data rate, lowlatency, robustness against fading used in 5G New Radio (NR). At the receiver end,the data arrives distorted due to disturbance during transfer over the wireless channel. LÄS MER

  4. 3. Experiments With Four Pattern Recognition Algorithms

    Kandidat-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Ayman Suliman; Joakim Bäverlind; [2017]
    Nyckelord :;

    Sammanfattning : A big part of computer vision concerns the issue ofhow well images can be classified into their corresponding classes.Image classification is a big part of reducing the gap betweenhuman and AI performance. Images are classified by first usinga dataset of images together with their given classifications totrain the system with machine learning. LÄS MER

  5. 4. Quantitative polymerase chain reaction method compared with traditional methods for Clostridium tyrobutyricum in grass-clover silage

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Madelene Eklund; [2017]
    Nyckelord :C. tyrobutyricum; qPCR; silage;

    Sammanfattning : C. tyrobutyricum is the most common type of bacteria to contaminate milk and cause late blown cheese caused by high spore counts in silage. The purpose of this thesis was to test a qPCR method to quantify C. LÄS MER

  7. 5. Calibration of fundamental diagrams for travel time predictions based on the cell transmission model

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Författare :Christoph Seybold; [2015]
    Nyckelord :Cell transmission model CTM ; Fundamental diagrams; Calibration; Dynamic sources; Dynamic sinks; Split ratios;

    Sammanfattning : Road traffic increases constantly and the negative consequences in the form of traffic jams can be realized especially in urban areas. In order to provide real time traffic information to road users and traffic managers, accurate computer models gain relevance. LÄS MER
