  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. Improved Precision Time Protocol with Relative Clock Phase Information

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Avneesh Vyas; [2020]
    Nyckelord :;

    Sammanfattning : A common time reference among nodes is one of the key requirements in telecommunication, distributed control systems and industrial automation systems. For instance, 3GPP LTE TDD standard requires at least ± 1.5 µsec time accuracy among base stations in order to resolve uplink and downlink transmission. LÄS MER

  4. 3. Machine Learning Based Modulation and Coding Scheme Selection

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

    Författare :Michel Chamat; Bersi Dimitrios Kodra; [2019]
    Nyckelord :Machine Learning; ML; Modulation and Coding Scheme; MCS; Scheduler; Scheduling; Technology and Engineering;

    Sammanfattning : In wireless communication, resources like bandwidth and energy are scarce and extremely valuable, any system should serve as many users as possible while preserving high Quality of Service (QoS) for the best user experience. Accordingly, the Base Station (BS) has the responsibility to optimally schedule its resources to the users based on the available information. LÄS MER

  5. 4. Beamforming in LTE FDD for Multiple Antenna Systems

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

    Författare :Atef Hatahet; Ankit Jain; [2018]
    Nyckelord :Beamforming; FDD; MIMO; LTE; AOA; Technology and Engineering;

    Sammanfattning : High data rate is still the most crucial factor in cellular systems, and with 5g approaching new techniques are studied to achieve higher bit rates. Using MIMO technology, the spatial domain was exploited through beamforming and multiplexing multiple users’ data together assured more spectrum efficiency which resulted in higher bit rates.

  7. 5. Intelligent Beam Weight Computation for Massive Beamforming

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Rohan Appilla Chakravarthula; Chaithanya Kumar Reddy Veluru; [2017]
    Nyckelord :;

    Sammanfattning : LTE (Long Term Evolution) is likely the most complex wireless system ever developed. It incorporates features that could not have been economically implemented as recently as a decade ago. Today, with large-scale ICs, LTE can be easily accommodated in base stations and battery-powered handsets alike. LÄS MER
