System Modeling and Simulation in 5G: A Hybrid Beamforming Approach With Power Flux Equalization in the Elevation Plane

This paper presents a 5G downlink system model for a hybrid multi-user beamforming technique at the base station. The presented technique employs power flux equalization in the elevation plane using a fixed analog cosecant-shaped beam and digital beamforming in the azimuth plane. The system performances of various beamforming algorithms are investigated via Monte-Carlo simulations by creating simultaneous co-frequency beams towards the randomly-located users. The simulation results show that the proposed cosecant subarray hybrid beamforming statistically performs better than the state-of-the-art hybrid beamforming techniques and provides reduced complexity.
