| Description: |
Objectives: Due to the high cost and power consumption of fully digital beamforming, the goal of this research is to thoroughly investigate Kalman-based beamformers in conjunction with existing beamformers for multicell multiuser scenarios. Methods: In this research work, Kalman based hybrid beamforming for millimeter wave massive MIMO along with existing linear beamformers has been investigated. Mathematical model for spectral efficiency has been developed for each linear beamformer under multicell multiuser scenario and the performance has been shown using MATLAB software. Findings: Simulation results show that all the beamformers perform better for multi-cell systems compared to single cell systems i.e. better spectral efficiency for a given signal to noise ratio has been achieved for multicell system. Simulation results also depict precoders spectral efficiency improved as the number of transmitting antennas increase and the number of users decrease for multicell multiuser scenario. Novelty: Expanding the kalman based beamformer that contains digital combiner for multicell multiuser scenario is the novelty of this research. Keywords: Hybrid Beamforming; Massive MIMO; Millimeter Wave; Multicell; Multiuser |
