Abstract (in Japanese) (See Japanese page) 
(in English) Multiple-input multiple-output (MIMO) relay systems have been
discussed in several published papers. When a relay node has only one antenna
element, the propagation environment is called keyhole. In this kind of
scenario the achievable channel capacity and link quality are decreased.
Another limit is when the number of the antenna elements of a relay node is larger than that of a MIMO transceiver, the channel capacity cannot be increased. In this paper, in order to obtain high channel capacity, the relay nodes are distributed in series. We optimize the position of each node for upper bound of channel capacity with each number of relay nodes. However, the relay nodes always can not be set at the desired location. Therefore, the transmit power and the distance between each relay node is necessary to be optimized for high channel capacity.
