| Abstract(in English) | This paper presents the indoor experiment using multiuser-Multiple Input Multiple Output testbed with a non-linear precoding scheme and the channel state information (CSI) feedback scheme proposed by the authors. As a non-linear precoding scheme, Tomlinson Harashima Precoding (THP) is applied, which achieves the high performance with the realistic computational complexity. The result of experiment shows that the spectrum efficiency of THP is 20% higher than that of conventional linear precoding. It is also revealed that the spectrum efficiency of THP is not degraded even in highly correlated channels. |
