  1. 1. 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

  3. 2. Time Synchronization for Full-Duplex Communications

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

    Författare :Ziyu Liu; Aamer Al-Hamwi; [2019]
    Nyckelord :Time Synchronization; In-band full-duplex; self-interference cancellation; Technology and Engineering;

    Sammanfattning : In-band full-duplex has emerged as an attractive solution for significantly enhancing the throughput of wireless communication systems by doubling the spectrum efficiency compared to conventional half-duplex systems. However, the existence of self-interference is a significant barrier to operate full-duplex systems. LÄS MER

  4. 3. Industrial Scenario using LTE Cellular Network

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

    Författare :Anthony Owondo; Javad Blouchi; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This Thesis project used an event-based simulation tool written in MATLAB that modelled a factory scenario. Multiple base stations and a varying number of nodes were modelled. The nodes send data to the base stations and the simulation tool calculates the SINR of the received data and uses this SINR to model a probability of error. LÄS MER

  5. 4. Propagation Modeling and LTE Network Performancein Real City Scenarios

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

    Författare :Sebastian Vestberg; [2018]
    Nyckelord :Propagation modeling; Network Simulations; LTE;

    Sammanfattning : Maps of chosen areas in Chicago, San José, London and Shibuya, areimported from Open Street Map into matlab in order to run LTE networksimulations for various scenarios. Firstly, two path loss models arecompared, the empirically based WINNER model and a set of sitespecificmodel. LÄS MER

  7. 5. Implementation and Benchmarking of a Crypto Processor for a NB-IoT SoC Platform

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

    Författare :Sébastien Fuhrmann; Luis Cavo; [2018]
    Nyckelord :3GPP; IoT; HLS; security; cryptography; AES; SNOW; ZUC; hardware; ASIC; confidentiality; integrity; cipher; Technology and Engineering;

    Sammanfattning : The goal of this Master’s Thesis is to investigate the implementation of cryptographic algorithms for IoT and how these encryption systems can be integrated in a NarrowBand IoT platform. Following 3rd Generation Partnership Project (3GPP) specifications, the Evolved Packet System (EPS) Encryption Algorithms (EEA) and EPS Integrity Algorithms (EIA) have been implemented and tested.
