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. Acceleration of Massive MIMO algorithms for Beyond 5G Baseband processing

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Ellen Nihl; Eek de Bruijckere; [2023]
   Keywords : embedded systems; massive MIMO; GPU; massive MIMO detection; Zero-Forcing algorithm; Cholesky decomposition; CUDA; 5G and Beyond;

   Abstract : As the world becomes more globalised, user equipment such as smartphones and Internet of Things devices require increasingly more data, which increases the demand for wireless data traffic. Hence, the acceleration of next-generational networks (5G and beyond) focuses mainly on increasing the bitrate and decreasing the latency. READ MORE

4. 3. Assessment of Exposure to Electromagnetic Fields from Distributed MIMO Antennas

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

   Author : Frans Nyberg Zou; [2022]
   Keywords : 6G; Distributed MIMO; Electromagnetic field exposure; Hybrid simulations; 6G; Distribuerad MIMO; Exponering av elektromagnetiska fält; Hybridsimueringar;

   Abstract : Research on 6G telecommunication networks has been initiated. Among all potential technology components, the distributed multi-input multioutput (D-MIMO) technology is one of the promising enablers. Due to the new technology solutions, additional methodologies for assessment of electromagnetic field (EMF) exposure need to be developed. READ MORE

6. 5. Approximate Inference Low-Complexity MIMO Detection

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

   Author : Joao Torres; [2019]
   Keywords : ;

   Abstract : In the telecommunications field, the correct detection of a certain signal is of most interest as it improves the robustness of the system. With multiple-input multiple-output (MIMO) antenna systems a new problem arises, the increase in complexity of the detection algorithms with the number of antennas. READ MORE
