3D-MIMO technology based on the active antenna array is an evolution of MIMO technology in LTE systems at present. It can make full use of space domain and further improve the performance of wireless communication system. Firstly, the technical features and the typical application scenes of 3D-MIMO technology were introduced. Then, a 3D dynamic beam forming algorithm based on SVD of channel state matrix was presented. In this algorithm, the two dimensions of base station antenna array and the SVD decomposed vector of channel matrix of the receiving antenna were combined to form a beam forming vector of the transmitter. Finally, the algorithm provides useful reference to the practical application of 3D-MIMO technology.
