  1. 1. Investigating and Modeling Uplink Processing in 5G NR Multisector Scheduler Simulator

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

    Författare :Oskar Nygren; Axel Sneitz-Björkman; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. LÄS MER

  3. 2. Codebook Based Multi-User MIMO for 5G

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

    Författare :Ralf Hajjar; Rahul Venkat Vissakodeti; [2019]
    Nyckelord :codebook type II; precoding for 5G; Technology and Engineering;

    Sammanfattning : Better signal strength is required to provide a good signal service to the UE. For this, different methods and techniques are available, one of them is codebook type II precoding. This method has a potential to provide an amount of energy to the user in the required direction more precisely than Codebook type I. LÄS MER

  4. 3. Predicting inter-frequency measurements in an LTE network using supervised machine learning : a comparative study of learning algorithms and data processing techniques

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Adrian Sonnert; [2018]
    Nyckelord :Telecommunications; Telecom; Mobile networks; 4G; LTE; LTE-A; Machine learning; Random forest; Gradient boosting; Neural network; Multi-layer perceptron; Logistic regression; Frequency measurements; Handover; Load balancing; Carrier aggregation;

    Sammanfattning : With increasing demands on network reliability and speed, network suppliers need to effectivize their communications algorithms. Frequency measurements are a core part of mobile network communications, increasing their effectiveness would increase the effectiveness of many network processes such as handovers, load balancing, and carrier aggregation.

  5. 4. Wireless system design : NB-IoT downlink simulator

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Piotr Krasowski; Douglas Troha; [2017]
    Nyckelord :nb-iot; lte; lte-a; downlink; simulator; wireless;

    Sammanfattning : The newly defined NB-IoT standard currently lacks a toolkit and simulator. In order to develop algorithms for this new standard there is a need for channels and signals as reference during tests. MATLAB is commonly used for testing LTE signals and therefore the toolkit was developed in this environment. LÄS MER

  7. 5. Direct Conversion Front End for LTE and LTE-A with Frequency-Translational Feedback, Harmonic Rejection Mixer and Input Matching Compensation

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

    Författare :Douglas Andersson Hägglund; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis covers the design of a wideband, flexible front end for LTE and LTE-A in a 65 nm CMOS process. A topology with global frequency translational feedback is investigated and a harmonic rejection mixer is implemented. LÄS MER
