  5. 4. Hierarchical Clustering based Dynamic Subarrays for Hybrid Beamforming Massive MU-MIMO

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

    Author : Francisco Goncalves Contente; [2020]
    Keywords : ;

    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.

  6. 5. 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.
