  1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

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

    Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  3. 2. Quantum Annealing Algorithms for PAPR Minimisation in Wireless Networks

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :David Bern; [2022]
    Nyckelord :Quantum Mechanics; Algorithms; Quantum Annealing; Graph representation;

    Sammanfattning : In this thesis, we devise a scheme to run PAPR minimisation with 3GPP EVM requirement as constraint on the D-Wave Systems’ quantum annealer. The PAPR minimisation is a problem central to optimising the costs and performance of wireless networks becoming increasingly difficult for larger OFDM-MIMO systems, while the EVM constraint needs to be satisfied to reach an industry standard performance.

  4. 3. D-band Power Amplifiers in Vertical InGaAs Nanowire MOSFET Technology for 100 Gbps Wireless Communication

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

    Författare :Patrik Blomberg; Ludvig Pile; [2022]
    Nyckelord :D-band; Power Amplifier; Pseudo-differential common source; Stacked; Vertical InGaAs nanowire; MOSFET; Technology and Engineering;

    Sammanfattning : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. LÄS MER

  5. 4. USER GENERATED CONTENT IN THE DESTINATION IMAGE PRESENTATION : THE DESTINATION VIENNA

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Natalie Lindgren; [2021]
    Nyckelord :UGC; SOR; EVM;

    Sammanfattning : UGC has become an important part of traveling both for the companies and for the travellers themselves. The topic is currently at its forefront of research, which makes the area of study even more relevant. Followed by the development of social media in the corporate world and especially its major part in the everyday life of Generation Y. LÄS MER

  7. 5. Implementering av EVM och Ganttschema,för stålhallsbolag

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för handel och företagande

    Författare :Filip Johansson; Rasmus Åkerstedt; [2021]
    Nyckelord :Byggprocess; EVM; Gantt-schema; Stålhallar; Projektstyrning;

    Sammanfattning : I dagens byggprojekt blir många byggen försenade och innehåller avvikelser som gör att budgeten inte kan upprätthållas. Företag inom branschen har inte alltid standardiserade sätt för att planera sina projekt. LÄS MER
