  1. 1. 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

  2. 2. Development of methods and software for rapid quality control in fluoroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Majid Khosamadi; [2021]
    Keywords : ;

    Abstract : Background: Fluoroscopy is a common imaging technique which uses X-ray to derive a real time imaging of patient anatomy to determine diagnosis and positioning of patients for interventional procedures. It is therefore important that the fluoroscopy systems maintain their performance. READ MORE

  3. 3. Hierarchical Clustering based Dynamic Subarrays for Hybrid Beamforming Massive MU-MIMO

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Francisco Goncalves Contente; [2020]
    Keywords : ;

    Abstract : Hybrid Beamforming in multiple input multiple output systems has surged in the past few years as the prime precoding architecture for massive MIMO systems since it addresses the systems performance and complexity/power consumption tradeoff. Most of the literature addresses HBF MIMO with a fixed antenna subarray, however it is possible to further increase the spectral efficiency of the system by dynamically configuring the HBF MIMO subarray according the channel state information of the users.

  4. 4. Analysis of stellar spectra with machine learning

    University essay from Lunds universitet/Institutionen för teoretisk fysik; Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Alvaro Segovia Otero; [2020]
    Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

    Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE

  5. 5. Implementation of adaptive filtering algorithms for noise cancellation

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Tanja Lampl; [2020]
    Keywords : ;

    Abstract : This paper deals with the implementation and performance evaluation of adaptive filtering algorithms for noise cancellation without reference signal. Noise cancellation is a technique of estimating a desired signal from a noise-corrupted observation. READ MORE
