3. 2. Hybrid Beamforming Design for Full-Duplex mmWave Relaying Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhe Wu; [2020]
   Keywords : mmWave; full-duplex; hybrid beamforming; self-interference cancellation; OMP; fast ADMM; convergence; mmwave; fullständig duplex; hybridstrålformning; självförstörande annullering; OMP; snabb ADMM; konvergens;

   Abstract : With the tremendous growth in the mobile data traffic, the demand for highdata rate is increasing rapidly, and higher frequency resources shall be exploredto alleviate the congestion in the overcrowded spectrum, thus, the millimeterwave (mmWave) frequency resource ranging from 30 GHz to 300 GHz has beenrecognized as a nature fit for the fifth-generation (5G) and beyond network. Tocompensate the severe path-loss in the mmWave band as well to realize theefficient transmissions by applying the low-cost architecture, it is of intereststo investigate the beamforming schemes with large-scale antenna arrays andthe full-duplex (FD) relaying strategy, which are indispensable in the operationof directional signal transmission and the efficient spectrum utilization inthe mmWave transmission, respectively.

4. 3. Codebook Based Multi-User MIMO for 5G

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

   Author : Ralf Hajjar; Rahul Venkat Vissakodeti; [2019]
   Keywords : codebook type II; precoding for 5G; Technology and Engineering;

   Abstract : Better signal strength is required to provide a good signal service to the UE. For this, different methods and techniques are available, one of them is codebook type II precoding. This method has a potential to provide an amount of energy to the user in the required direction more precisely than Codebook type I. READ MORE

5. 4. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems

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

   Author : Hesham Sharkas; Haruhi Echigo; [2019]
   Keywords : 5G; Beamforming; Beam-forming; Beam Management; Beam Searching; Beam Sweeping; Codebook; code-book; Initial Access; MIMO; MillimeterWave; millimeter wave; mmWave; mm-Wave; mm Wave; Precoding; Slepian Beam; Synthesizer; Beam Synthesizer; Technology and Engineering;

   Abstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE

6. 5. 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
