  1. 1. Sparse Approximation of Spatial Channel Model with Dictionary Learning

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

    Författare :Matilda Zhou; [2022]
    Nyckelord :Spatial channel model SCM ; dictionary learning; compressive sensing CS ; discrete Fourier transform DFT ; overcomplete discrete Fourier transform ODFT ; Rumslig kanalmodell; ordbokslärning; kompressionsavkänning; diskret Fourier-transform; överkomplett diskret Fourier-transform;

    Sammanfattning : In large antenna systems, traditional channel estimation is costly and infeasible in some situations. Compressive sensing was proposed to estimate the channel with fewer measurements. Most of the previous work uses a predefined discrete Fourier transform matrix or overcomplete Fourier transform matrix to approximate the channel. LÄS MER

  3. 2. Sensor concepts for Industry 4.0

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell Produktion

    Författare :Daniel Le; [2021]
    Nyckelord :Fluorescence; alumina; ruby; piezo-spectroscopic effect; Technology and Engineering;

    Sammanfattning : The next industrial revolution has been denoted by Industry 4.0 and is the continuation of the process of knowledge acquisition and further control over the entire production process which has been evolving since the beginning of the industrialization. A paramount driver of Industry 4.0 is the smart sensor. LÄS MER

  4. 3. Reconstruction of Hyperspectral Images Using Generative Adversarial Networks

  7. 5. Stand-alone Dual Sensing Single Pixel Camera in SWIR

    Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Martin Oja; Sebastian Olsson; [2019]
    Nyckelord :Single Pixel Camera; SWIR; Compressive Sensing; Single Pixel Imaging; Image Reconstruction;

    Sammanfattning : A Single pixel camera is just that, a camera that uses only a single pixel to take images. Though, it is a bit more to it than just a pixel. It requires several components which will be explained in the thesis. LÄS MER
