  1. 1. Machine Learning-based MIMO Indoor Positioning

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

    Author : Qiyi Chen; [2023]
    Keywords : Technology and Engineering;

    Abstract : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. READ MORE

  3. 2. Modelling and Investigation of Control of a Power Infrastructure Resource Management System for a Radio Base Station : A study on sustainable power management for ICT infrastructure.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Lenart; [2023]
    Keywords : Hybrid Dynamical Systems; Resource Management; Hybrid Automaton; Sustainable solutions for Wireless technology; Hybrid Dynamiska System; Resurshantering; Hybrid Automaton; Hållbara lösningar för trådlös teknologi;

    Abstract : In order to minimize greenhouse gas emissions and operational cost related to the ICT-infrastructure the power management method of a Radio Base Station (RBS) or Base Transceiver Station (BTS) at Ericsson is studied and modelled. The major load demand at RBS’s are due to uplink and downlink data traffic. READ MORE

  4. 3. Performance Analysis Of Massive MIMO With Port Reduction

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tingrui Zhang; [2022]
    Keywords : 5G NR; Massive MIMO; Fronthaul; Beamforming; Functional split; 5G NR; Massive MIMO; Fronthaul; Beamforming; funktionell uppdelning;

    Abstract : In centralized radio access network (C-RAN) architecture, the base-band unit (BBU) is connected to one or more remote radio units (RRUs) via a fronthaul (FH) interface. Upgrading base station antennas in C-RAN to support massive multiple-input multiple-output (MIMO) technology can improve network spectral efficiency and largely boost the capacity of the 5G system.

  5. 4. Millimeter Wave Antenna Array Calibration and Validation for 5G New Radio Access

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

    Author : Manuel Jose Lopez Morales; [2018]
    Keywords : Technology and Engineering;

    Abstract : This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. READ MORE

  6. 5. Radio Localization with GSM

    University essay from Linköpings universitet/Reglerteknik

    Author : Simon Pålstam; [2016]
    Keywords : Radio Localization; GSM; Fake Base Station; FBS; TOA; RSS;

    Abstract : This thesis presents a feasibility study on unobtrusive localization of GSM en- abled cellphones using a Fake Base Station (FBS). An FBS is a radio transceiver that emulates the behaviour of a legitimate GSM Base Station (BS) to fool unal- tered cellphones to connect with it. READ MORE
