  1. 1. Enhancing the Decoding of Short LDPC Codes with Stochastic Sequences

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

    Author : Yuyuan Gu; Haien Li; [2021]
    Keywords : 5G; channel coding; LDPC codes; stochastic decoding; stochastic computation; Technology and Engineering;

    Abstract : Low-Density Parity-Check (LDPC) codes are one of the most popular codes used in nowadays’ communication due to their high coding efficiency at low decoding complexity. With these characteristics, LDPC codes are suitable for high-speed information transmission systems. READ MORE

  3. 2. Graph Neural Networks and Learned Approximate Message Passing Algorithms for Massive MIMO Detection

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

    Author : Andrea Scotti; [2020]
    Keywords : ;

    Abstract : Massive multiple-input and multiple-output (MIMO) is a method to improvethe performance of wireless communication systems by having a large numberof antennas at both the transmitter and the receiver. In the fifth-generation(5G) mobile communication system, Massive MIMO is a key technology toface the increasing number of mobile users and satisfy user demands. READ MORE

  4. 3. 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. 4. Performance Evaluation of Stereo Reconstruction Algorithms on NIR Images

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Dario Vidas; [2016]
    Keywords : stereo vision; stereo reconstruction algorithms; near-infrared images; algorithm performance evaluation;

    Abstract : Stereo vision is one of the most active research areas in computer vision. While hundreds of stereo reconstruction algorithms have been developed, little work has been done on the evaluation of such algorithms and almost none on evaluation on Near-Infrared (NIR) images. READ MORE

  6. 5. Finding Implicit Citations in Scientific Publications : Improvements to Citation Context Detection Methods

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Jonathan Murray; [2015]
    Keywords : implicit citations; citation context; citations; natural language processing; nlp; machine learning; belief propagation;

    Abstract : This thesis deals with the task of identifying implicit citations between scientific publications. Apart from being useful knowledge on their own, the citations may be used as input to other problems such as determining an author’s sentiment towards a reference, or summarizing a paper based on what others have written about it.
