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

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : David Adolfsson; [2023]
    Keywords : Channel Estimation; 5G NR; CNN; Kanalestimering; 5G NR;

    Abstract : 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. READ MORE

  3. 2. Technologies and Evaluation Metrics for On-Board Over the Air Control

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Aneysha Datta; [2022]
    Keywords : Wireless; Performance Metrics; WAVE; DMG; Intra-Vehicular Communication; BER; Simulink; Model-Based Design;

    Abstract : This project has been carried out at the Electronic Embedded Systems Architecture Department at Volvo Construction Equipment (VCE), Eskilstuna, Sweden. It forms the baseline for a stepwise systematic research initiative to convert wired technologies used for certain in-vehicle control and communication components to wireless technologies. READ MORE

  4. 3. Synchronization of Distributed Units without Access to GPS

    University essay from Linköpings universitet/Datorteknik

    Author : Erik Carlsson; [2018]
    Keywords : Timing algorithm; Communications system; QPSK; FPGA; VHDL;

    Abstract : Time synchronization between systems having no external reference can be an issue in small wireless node-based systems. In this thesis a transceiver is designed and implemented in two separate systems. Then the timing algorithm of "TwoWay Time Transfer" is then chosen to correct any timing error between the two free running clocks of the systems. READ MORE

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

    University essay from Uppsala universitet/Signaler och System

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

    Abstract : 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. READ MORE

  6. 5. Characterization of NI-USRP System

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

    Author : Xubo Fu; [2014]
    Keywords : NI-USRP; Labview; Characterization; SNR; digital modulation; PSK;

    Abstract : Nowadays the rapid developments of wireless communication technologies there are more and more ways to look into the RF measurements and designs in detail such as Universal Software Radio Peripheral(USRP) from LabVIEW, Advance Design System(ADS),etc.Moreover a lack of measurements what compared with different digital modulation schemes is becoming a problem.
