Hybrid Beamforming for Millimeter Wave Massive MIMO Using Singular Value Decomposition

Beamforming is an essential process in 5G networks and beyonde, with the aim of overcoming the obstacles resulting from the adoption of millimeter waves to transmit data, which suffer from large path loss and are affected by various obstacles. Also, in order to deal with these characteristics, a large number of (Massive MIMO) antennas must be adopted, which makes it difficult to rely on digital beamforming due to the energy constraints resulting from the necessity of having a radio chain for each antenna, which has pushed towards developing hybrid beamforming algorithms. In this paper, we will study the performance of hybrid beamforming based on the Singular value Decomposition (SVD) method, in terms of spectrum efficiency and bit error rate compared with full digital beamforming case, and we will study the effect of increasing the number of transmitter and receiver antenna and the number of RF chains.
