  1. 11. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Marie Defives; [2022]
    Nyckelord :Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Sammanfattning : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. LÄS MER

  3. 12. Performance analysis of adaptive streaming algorithms for a low-latency environment

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

    Författare :Antonio Kevo; Albert Sjölund; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Streaming video over the internet can face issues when met with poor and varying network conditions, which can be especially noticeable when streaming live video such as security footage or video calling. To handle this, there exists congestion control algorithms that monitor network conditions based on feedback from the receiver and adapt the video output. LÄS MER

  4. 13. Efficient High-level Synthesis Implementation of massive MIMO Processing on RFSoC

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

    Författare :Sijia Cheng; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Massive multiple-input multiple-output (MIMO) refers to a wireless access technology that equips base station (BS) with hundreds to thousands of antennas to serve tens of user equipment (UE) in the same time-frequency resource. These extensive antennas improve spectral and energy efficiency, but the detection algorithms tend to be more complex with operations, multiplications, and inversions on larger size matrix. LÄS MER

  5. 14. Evaluation, Optimization and Characterization of Miniaturized Triple Band Antennas for Wi-Fi 6 and Wi-Fi 6E

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

    Författare :Muzi Cheng; [2022]
    Nyckelord :Antennas; Wi-Fi 6E; Radiation; Resonance; Tuning; Antenner; Wi-Fi 6E; Strålning; Resonans; Tuning;

    Sammanfattning : Antenna is a key component in wireless devices such as cell phones, laptops and smartwatches. With the new generation of Wi-Fi technology: Wi-Fi 6E coming out, 1200MHz bandwidth from 5.925GHz to 7.125GHz is freed for use. LÄS MER

  7. 15. Finding Locally Unique IDs in Enormous IoT systems

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Sebastian Yngman; [2022]
    Nyckelord :IoT; Internet of Things; Graph Coloring; Optimization;

    Sammanfattning : The Internet of Things (IoT) is an important and expanding technology used for a large variety of applications to monitor and automate processes. The aim of this thesis is to present a way to find and assign locally unique IDs to access points (APs) in enormous wireless IoT systems where mobile tags are traversing the network and communicating with multiple APs simultaneously.
