Two-Dimensional Doa Estimation For 5g Networks

Mobile communication is coming to the fifth generation (5G) networks. In the age of 5G, the three-dimensional (3D) beamforming is one of the highlighted technologies. 3D beamforming increases vertical dimension in terms of space domain, but also has brought a challenge to beamforming, especially the problem of direction-of-arrival (DOA) estimation. In this paper, a DOA estimation method based on multiple signal classification (MUSIC) of uniform circular array (UCA) with mutual coupling compensation is presented for the future 5G networks. 2D MUSIC does well in estimating DOA without an accurate number of signals. The MATLAB software is employed in order to conduct the modeling and 2D MUSIC algorithm simulations.
