   Sammanfattning : 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. LÄS MER

5. 4. Channel Estimation and Power Control Algorithms in the Presence of Channel Aging

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

   Författare :Yan Bixing; [2023]
   Nyckelord :Fading channel; auto-regressive model; power allocation; uncrewed aerial vehicle networks; Fading kanal; auto-regressiv modell; krafttilldelning; obemannade flygfordonsnätverk;

   Sammanfattning : Power allocation algorithms that determine how much power should be allocated to pilot and data symbols play an important role in addressing the trade-off between accurate channel estimation and high high spectral efficiency for data symbols in the presence of time-varying fading channels. Dealing with this trade-off is highly non-trivial when the channel changes or ages rapidly in time. LÄS MER

7. 5. Diagnostics Framework for Time-Critical Control Systems in Cloud-Fog Automation

   Master-uppsats, Mälardalens universitet/Inbyggda system

   Författare :Johannes Deivard; Valentin Johansson; [2022]
   Nyckelord :Cloud-fog automation; distributed control systems; network diagnostics; process diagnostics; process mining; Industrial Internet of Things; Industry 4.0; network probing; wireless telecommunication; 5G; WiFi 6; eBPF;

   Sammanfattning : Evolving technology in wireless telecommunication, such as 5G, provides opportunities to utilize wireless communication more in an industrial setting where reliability and predictability are of great concern. More capable Industrial Internet of Things devices (IIoT) are, indeed, a catalyst for Industry 4.0. LÄS MER
