| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A significant challenge of the multiuser multiple-input multiple-output (MIMO) is the interference leakage among user terminals caused by the channel time variation due to their mobility, which significantly degrades the transmission performance. In massive MIMO using hundreds of antenna elements at the base station side, null-space expansion is previously proposed to improve the robustness of multiuser spatial multiplexing even under the mobility environment. It performs null-steering to past interference channel state information, fully exploiting the huge spatial degree of freedom that massive antenna elements bring. Its performance depends on the distribution of spatial degrees of freedom used for beam/null-steering. Focusing on the above viewpoints, this paper introduces various methods for further performance improvement. |
