  1. 1. Beamforming in LTE FDD for Multiple Antenna Systems

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

    Author : Atef Hatahet; Ankit Jain; [2018]
    Keywords : Beamforming; FDD; MIMO; LTE; AOA; Technology and Engineering;

    Abstract : High data rate is still the most crucial factor in cellular systems, and with 5g approaching new techniques are studied to achieve higher bit rates. Using MIMO technology, the spatial domain was exploited through beamforming and multiplexing multiple users’ data together assured more spectrum efficiency which resulted in higher bit rates.

  3. 2. 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

  4. 3. 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.

  5. 4. Design and implementation of LTE-A and 5G kernel algorithms on SIMD vector processor

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Jiabing Guo; [2015]
    Keywords : channel estimation; MIMO detection; massive complex matrix inversion; SIMD; kanaluppskattning; MIMO-detektion; massiva komplex matrisinversion; SIMD;

    Abstract : With the wide spread of wireless technology, the time for 4G has arrived, and 5G will appear not so far in the future. However, no matter whether it is 4G or 5G, low latency is a mandatory requirement for baseband processing at base stations for modern cellular standards. READ MORE

  6. 5. Iterative Channel Estimation in LTE Uplink

    University essay from KTH/Kommunikationsteori

    Author : Erik Lindén; [2014]
    Keywords : ;

    Abstract : An algorithm for iterative channel estimation using soft feedback for LTE uplink is proposed. The algorithm has low complexity compared to MMSE estimation and does not require knowledge of the channel statistics. READ MORE
