Abstract
The research on distributed MIMO relay system has been attracting much attention. By optimizing the position of each relay, the channel capacity of such system is larger than that of original MIMO system. However, the propagation environment between each transceiver is simplified to be the same. In this paper, a decode-and-forward scheme distributed MIMO relay system is examined. The distance between each relay is optimized in propagation environment which is brought close to actuality. For upper bound of channel capacity, 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 such method the transmit power and relay is saving. © 2011 IEEE.
