Beamforming is an essential process in 5G networks, 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 beam forming algorithms. In this paper, we will study the mechanism of hybrid beamforming based on the Singular value Decomposition method, and we will simulate the system based on this method and compare its performance with the case of full digital beamforming..
