    Sammanfattning : 5G supports enormous increase in data rate. Massive antenna beamforming is expected to play a key role in increasing capacity in case of multi-user MIMO and coverage in case of single-user MIMO. LÄS MER

  5. 4. Scheduler Algorithms for MU-MIMO

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Sammanfattning : 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. LÄS MER

  7. 5. Development and Evaluation of UTDoAas a Positioning Method in LTE

    Master-uppsats, KTH/Signalbehandling

    Författare :Thomas Arthur Herbert Bressner; [2015]
    Nyckelord :LTE; TDoA; TDOA; Positioning; UTDoA; UTDOA; Thomas Bressner; Bressner;

    Sammanfattning : Although positioning has been one of the main target study areas in mobile communication in the last decade, it still receives strong attention in recent years focusing more on the indoor users. Nowadays, a wide range of different methods are available to estimate the position of the target user under certain circumstances. LÄS MER
