| Abstract(in English) | In order to realize high capacity communication, massive multiple-input multiple-output (MIMO) systems which have a very large number of antenna elements at a base station (BS) or an access point (AP) have been studied for future cellular systems. It is, however, difficult to build the massive MIMO system because the installation space is limited. To cope with this limitation, a full-dimension MIMO (FD-MIMO) system where antenna elements are placed on a 2D grid at the BS or AP for MIMO transmission is proposed. The 2D antenna array saves the space and allows elevation beamforming as well as azimuth beamforming. In this paper, we evaluate performance of the FD-MIMO in indoor Line-of-Sight environments compared with that of a ID antenna arrangement using a ray tracing technique which enables to obtain channel matrices between BS and user terminals. It has been shown that FD-MIMO with a small rectangular antenna array performs better than ID antenna array when users are located near the BS. |
