  1. 1. Quantum Error Correction Using Graph Neural Networks

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Valdemar Bergentall; [2021-06-17]
    Keywords : Quantum error correction; surface code; graph neural networks;

    Abstract : A graph neural network (GNN) is constructed and trained with a purpose of usingit as a quantum error correction decoder for depolarized noise on the surface code.Since associating syndromes on the surface code with graphs instead of grid-likedata seemed promising, a previous decoder based on the Markov Chain Monte Carlomethod was used to generate data to create graphs.

  2. 2. Beamforming router as relay to increase 5G cell coverage

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap;

    Author : Jhansi Dunuka; Nikolai Panagiotou; [2021]
    Keywords : Beamforming; MIMO; 5G; NR; Direction of Arrival; Relay;

    Abstract : The growing traffic and global bandwidth shortage for broadband cellular communi-cation networks has motivated to explore the underutilized millimeter wave frequencyspectrum for future communications. Fifth generation (5G) is the key to empow-ering new services and use cases for people, businesses, and society at large. READ MORE

  3. 3. Anomaly detection in 5G beam propagation

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

    Author : Katarina Hellgren; Phiphi Tran; [2021]
    Keywords : Machine learning; wireless communication; 5G; beam propagation; DBSCAN; KNN; anomaly detection; clustering; Technology and Engineering;

    Abstract : Advancements in today's technology has motivated invention of faster mobile communication systems. The fifth generation mobile network, 5G, is the latest version made by the third generation partnership project (3GPP) and expects to both increase connection speed and reduce latency, which eventually will make it applicable in supporting state-of-the art technologies such as virtual reality and self-driving vehicles among others.

  4. 4. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Farhan Akram; [2021]
    Keywords : SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Abstract : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. READ MORE

  5. 5. Classification of EEG Data Using Convolutional Neural Networks and the Scaled Reassigned Spectrogram

    University essay from Lunds universitet/Matematisk statistik

    Author : Karin Pagels; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : Electroencephalography (EEG) is a medical technique for measuring brain activity through several channels connected to the scalp. Interpreting EEG data is a difficult problem because of the large amount of noise contained in the data. READ MORE
