  1. 1. A Conjugate Residual Solver with Kernel Fusion for massive MIMO Detection

    University essay from Högskolan i Halmstad/Centrum för forskning om tillämpade intelligenta system (CAISR)

    Author : Ioannis Broumas; [2023]
    Keywords : MIMO; massive MIMO; GPU; CUDA; Software Defined Radio; SDR; MMSE; ZF; zero-forcing; parallel detection; iterative methods; conjugate residual; parallel computing; kernel fusion;

    Abstract : This thesis presents a comparison of a GPU implementation of the Conjugate Residual method as a sequence of generic library kernels against implementations ofthe method with custom kernels to expose the performance gains of a keyoptimization strategy, kernel fusion, for memory-bound operations which is to makeefficient reuse of the processed data. For massive MIMO the iterative solver is to be employed at the linear detection stageto overcome the computational bottleneck of the matrix inversion required in theequalization process, which is 𝒪(𝑛3) for direct solvers.

  3. 2. Comparative investigation of micromechanisms of plastic deformation by in-situ tensile tests of highly textured 316L steel

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Subhani Kumarasinghe; [2022]
    Keywords : Additive manufacturing; texture control; plastic deformation;

    Abstract : Additive manufacturing (AM) is identified as one of the best techniques in manufacturing components addressing most of the current challenges including material scarcity, design complexity, material compatibility, etc. Stainless steel 316L is one of the promising material candidates in AM due to its extraordinary properties that are useful in a wide variety of industries.

  4. 3. Radar and Optical Data Fusion for Object Based Urban Land Cover Mapping

    University essay from KTH/Geodesi och geoinformatik

    Author : Alexander Jacob; [2011]
    Keywords : Data Fusion; Image Segmentation; Object based Mapping; Urban Land Cover; SAR; Radar; Multispectral; Region growing and merging;

    Abstract : The creation and classification of segments for object based urban land cover mapping is the key goal of this master thesis. An algorithm based on region growing and merging was developed, implemented and tested. The synergy effects of a fused data set of SAR and optical imagery were evaluated based on the classification results. READ MORE
