2. Hierarchical Clustering based Dynamic Subarrays for Hybrid Beamforming Massive MU-MIMO
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Hybrid Beamforming in multiple input multiple output systems has surged in the past few years as the prime precoding architecture for massive MIMO systems since it addresses the systems performance and complexity/power consumption tradeoff. Most of the literature addresses HBF MIMO with a fixed antenna subarray, however it is possible to further increase the spectral efficiency of the system by dynamically configuring the HBF MIMO subarray according the channel state information of the users.

3. Hybrid Beamforming Design for Full-Duplex mmWave Relaying Systems
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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. Low Complexity Beamformer structures for application in Hearing Aids
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : Background noise is particularly damaging to speech intelligibility for people with hearing loss. The problem of reducing noise in hearing aids is one of great importance and great difficulty. Over the years, many solutions and different algorithms have been implemented in order to provide the optimal solution to the problem. READ MORE

5. Optimized Codebook Based Hybrid Beamforming
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : In this thesis we research beamforming capabilities of the UEs equipped with several antennas in a 5G scenario. We define a system model based on the use of phase codebooks that allow to change the radiation patterns of the arrays of antennas installed in the UE. READ MORE
