  1. 6. Methods of self-interference cancellation in full duplex telecommunication systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Erlandsson; Viktor Sköldheden; [2021]
    Keywords : telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

    Abstract : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. READ MORE

  3. 7. Time Synchronization for Full-Duplex Communications

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

    Author : Ziyu Liu; Aamer Al-Hamwi; [2019]
    Keywords : Time Synchronization; In-band full-duplex; self-interference cancellation; Technology and Engineering;

    Abstract : In-band full-duplex has emerged as an attractive solution for significantly enhancing the throughput of wireless communication systems by doubling the spectrum efficiency compared to conventional half-duplex systems. However, the existence of self-interference is a significant barrier to operate full-duplex systems. READ MORE

  4. 8. User Equipment Characterization using Machine Learning

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

    Author : Vanessa Fakhoury; Xin Zhou; [2019]
    Keywords : machine learning; characterization; massive MIMO; beamforming; neural networks; support vector machine; logistic regression; multiclass neural networks; Technology and Engineering;

    Abstract : With the ever increasing demand for higher data rates and reliability, efficient management of cellular networks remains a challenge. Among other technologies, fifth generation systems are expected to tackle this challenge using large electronically controllable antenna arrays operating in the time division duplex mode. READ MORE

  5. 9. Machine Learning Based Modulation and Coding Scheme Selection

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

    Author : Michel Chamat; Bersi Dimitrios Kodra; [2019]
    Keywords : Machine Learning; ML; Modulation and Coding Scheme; MCS; Scheduler; Scheduling; Technology and Engineering;

    Abstract : In wireless communication, resources like bandwidth and energy are scarce and extremely valuable, any system should serve as many users as possible while preserving high Quality of Service (QoS) for the best user experience. Accordingly, the Base Station (BS) has the responsibility to optimally schedule its resources to the users based on the available information. READ MORE

  6. 10. Scheduler Algorithms for MU-MIMO

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

    Author : Wissam Moustafa; Richard Mugisha; [2017]
    Keywords : Scheduling; Beamforming; TDD; TM-8; SRS; Downlink; Round Robin; SU-MIMO; MU-MIMO.; Technology and Engineering;

    Abstract : In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. READ MORE
