Since 5G systems are pushing the boundaries for cellular communications by introducing unique challenges such as multiple beam antennas, beamforming etc. in the field of antenna design. Although separate studies do exist on these challenges, the concept antenna synthesis using different disciplines is relatively new. This work presents a 5G simulation model using a recently proposed hybrid beamforming technique employing cosecant power flux equalization in elevation plane with digital beamforming in azimuth plane. Various beamforming algorithms in azimuth domain are investigated for concurrent users sharing same frequency spectrum and their impact on system performance such as signal to interference plus noise ratio (SINR) is statistically analyzed. Moreover, the impact of antenna sidelobe levels on system SINR performance is investigated in detail. The simulation results shows that the cosecant subarray hybrid beamforming performs better than traditional hybrid beamforming in terms of SINR for cell edge users. In addition to that, this work provides a unique perspective to systemengineers for intuitively analyzing the impact of antenna system on communication link and to derive design requirements that would be crucial in the antenna system synthesis Subject 5G Cellular SystemsZero Forcing beamformingMinimum Mean Square Error BeamformingCosecant power flux equalization BeamformingOrthogonal Matching Pursuit Algorithm To reference this document use: http://resolver.tudelft.nl/uuid:3d56b831-98b5-462b-9a54-e3b1b66c4fa5 Part of collection Student theses Document type master thesis Rights © 2018 Salman Salman Files PDF Thesis_Report_new.pdf 3.25 MB Close viewer /islandora/object/uuid:3d56b831-98b5-462b-9a54-e3b1b66c4fa5/datastream/OBJ/view
