Abstract :
A massive multiple-input multiple-output (MIMO) system, which has a very large number of antenna elements at the base station (BS), is a promising technology for future high-speed, high-capacity communication systems. However, it faces a serious issue of limited installation space. To cope with this limitation, a full-dimension MIMO (FD-MIMO) system has been proposed. This system can save installation space as well as control the azimuth and elevation beamforming because the antenna elements are arranged in a two-dimensional (2D) array. In this paper, we evaluate the performance of FD-MIMO in indoor line-of-sight environments by comparing it with a linearly arranged array, that is, a one-dimensional (1D) array. The channel matrices for the evaluations are obtained by using a ray-tracing technique. The results reveal that the FD-MIMO system with a small rectangular 2D array outperforms a 1D array when users are located near the BS.
