  1. 1. Stability and Controllability of Diffusion Models

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Anton Mörtberg; [2023]
    Nyckelord :Turing Reaction and Diffusion model; System stability; Kronecker product; System controllability;

    Sammanfattning : Alan Turing explored how patterns emerged in embryos. The modelsexplained by Turing describe how two morphogens interact with eachother and develop certain patterns though different conditions. LÄS MER

  3. 2. Reconstruction of past European land cover from pollen data: using spatial statistics and Crank-Nicolson Monte Carlo

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Lovisa Svensson; [2019]
    Nyckelord :Pollen data; compositional data; Dirichlet distribution; spatio-temporal reconstruction; Kronecker product; Gaussian Markov random field GMRF ; Markov Chain Monte Carlo MCMC ; Metropolis Hastings MH ; Metropolis adjusted Langevin algorithm MALA ; Mathematics and Statistics;

    Sammanfattning : Given a pollen data set from Europe over a time period, the aim is to reconstruct the past land cover by interpolating from the pollen data values to a continuous map. The data is on compositional form with three vegetation categories; coniferous forest, broadleaved forest and open land. LÄS MER

  4. 3. Estimation of Statistical Properties in a Mobile MIMO System

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

    Författare :Torsten Molitor; Hilding Wollbo; [2018]
    Nyckelord :;

    Sammanfattning : Several measures to evaluate the stationarity of a MIMO radio channel are proposed and implemented. The analysis is performed on a Kronecker model implementation of the channel matrix covariance, which describes the statistical characteristics and transmission properties of the radio channel.

  5. 4. A Study of Lattice Reduction Detection Techniques for LTE Systems

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

    Författare :Liping Wang; [2016]
    Nyckelord :LTE; MIMO; Lattice Reduction; MMSE; ZF; ML; Kronecker Model; Rayleigh Fading Channel; Technology and Engineering;

    Sammanfattning : MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. LÄS MER

  7. 5. Massive MIMO Channel Modeling

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

    Författare :Yongchun Wang; Xin You; [2015]
    Nyckelord :massive MIMO; 5G; channel modeling; the Kronecker model; the Weichselberger model; capacity; sum-rate; singular value spread; the Random Cluster Model; cluster; spatial correlation; large-scale fading; Technology and Engineering;

    Sammanfattning : Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e. LÄS MER
