  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. Block Diagonalization Based Beamforming

    University essay from KTH/Teknisk informationsvetenskap

    Author : Darshan Patil; [2017]
    Keywords : ;

    Abstract : With increasing mobile penetration multi-user multi-antenna wireless communication systems are needed. This is to ensure higher per-user data rates along with higher system capacities by exploiting the excess degree of freedom due to additional antennas at the receiver with spatial multiplexing.

  4. 3. Low-PAR Precoding for Very-Large Multi-User MIMO Systems

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska högskolan

    Author : Christopher Mollén; [2013]
    Keywords : MIMO; PAR Reduction; Precoding; Multi-User; MIMO; toppvärdesreducering; förkodning; fleranvändarförkodning;

    Abstract : Storskaliga fleranvändar-MIMO-system, med hundratals basstationsantenner, studeras med allt större intresse både inom akademin och industrin. En anledning är att sådana system kan betjäna flera enantennsanvändare samtidigt över samma tids-frekvens-resurs med fleranvändarförkodning. READ MORE

  5. 4. Linear Precoding Performance of Massive MU-MIMO downlink System

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Eakkamol Pakdeejit; [2013]
    Keywords : Massive MU-MIMO; Multiuser-MIMO; Linear precoding; Spectral efficiency; Energy efficiency;

    Abstract : Nowadays, multiuser Multiple-In Multiple-Out systems (MU-MIMO) are used in a new generation wireless technologies. Due to that wireless technology improvement is ongoing, the numbers of users and applications increase rapidly. Then, wireless communications need the high data rate and link reliability at the same time. READ MORE

  6. 5. Evaluation of Particle Swarm Optimization Algorithm for Precoding in Coordinated Multi-Point System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Amir Shehni; [2013]
    Keywords : Index Terms--- Coordinated Multi-Point; Precoding; Particle Swarm Optimization; Stochastic Optimization;

    Abstract : In future communication system, the constraint of recourse allocation are a challenging topic. One way for observing such constraint is to apply frequency reuse factor of one in commu- nication system. Taking this factor to one causes the system to have serious problems such as small sum rate and interference speci cally at cell-edge. READ MORE
