ABSTRACT: The research on distributed MIMO relay system has been
attracting much attention. In this paper, a decode-and-forward scheme
distributed MIMO relay system is examined. For upper bound of channel capacity,
the distance between transceivers is optimized when the propagation loss is
brought close to actuality. Additionally, the number of relay is optimized
whether total antenna element is fixed or not. When the number of relay is assumed
to be infinite, the dynamic relay selection method based on the transmission
rate is proposed. We represent that with the proposed method, the transmit power
and the number of relays are saving.
