  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.

  2. 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

  3. 3. Beyond 5G Baseband Processing on Epiphany Architecture

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Yash Sawant; [2021]
    Keywords : ;

    Abstract : Massive Multiple Input Multiple Output (mMIMO) is a key technology for wireless communications. The concept behind the technology is using a large number of antennas at the base station which servers multiple user equipment simultaneously. READ MORE

  4. 4. 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

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

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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. READ MORE
