  1. 1. Simulation and Testing of a MU-MIMO Beamforming System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Keywords : Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Abstract : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. READ MORE

  3. 2. Measurements, Estimations and Calibration with a Fully Digital Array

    University essay from Uppsala universitet/Signaler och system

    Author : Oscar Magnér; [2023]
    Keywords : WiDAR; signal processing; digital array; broadband antenna; array antenna; antenna; calibration; direct sampling; antenn; bredbandig; digital array; array antenn; direktsampling; signalbehandling; kalibrering; WiDAR; Saab AB; SAAB;

    Abstract : In modern digital communication, transmission and reception of information through electromagnetic signals requires digital devices that can process high data rates accurately despite being located in information heavy environments. One type of antenna receiver is the digital antenna array, which can steer its lobes electronically to increase or decrease sensitivity in specific directions. READ MORE

  4. 3. Nötboskap i en geografiskt avgränsad distributionskedja : en kvalitativ fallstudie om lokalproducerat nötkött och dess mervärden

    University essay from SLU/Dept. of Economics

    Author : Izabelle Fahlgren; Amanda Larsson; [2022]
    Keywords : Distributionskedja; lokalproducerat; mervärden; nötboskap; närproducerat;

    Abstract : Coronapandemin har bidragit till att fler konsumenter fått ett större allmänt intresse kring lokalproducerade livsmedel. Det kan gynna den geografiska samhörigheten i form av en ökad sysselsättning och en levande landsbygd. Det kan också stimulera den lokala ekonomin, då produktionen och försäljning stannar i närområdet. READ MORE

  5. 4. Positioning in Non-Terrestrial Networks

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Soha Emara; [2021]
    Keywords : positioning; 5G; satellite; NTN; Technology and Engineering;

    Abstract : In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. READ MORE

  6. 5. LPI waveforms for AESA radar

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Andreas Sjöberg; [2020]
    Keywords : Radar LPI waveform AESA;

    Abstract : The purpose of low probability of intercept (LPI) radar is, on top of the standard requirements on a radar, to remain undetected by hostile electronic warfare (EW) systems. This can be achieved primarily by reducing the amount of radiated power in any given direction at all times and is done by transmitting longer modulated pulses that can then be compressed digitally in order to retain range resolution.
