  1. 1. 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

  3. 2. Design of VoIP Paralleled Client-Server Software for Multicore

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Zeeshan Khan; [2013]
    Keywords : ;

    Abstract : As "Voice over IP" has become more prevalent and many client and server applications have been designed for them, the VoIP industry has seen the need for faster, more capable systems to keep up. Traditionally, system speed-up has been achieved by increasing clock speeds but, conventional single-core CPU clock rates have peaked a few years ago due to very high power consumption and heating problems.
