摘要：

Energy harvesting, which is a promising technology to prolong the lifetime of energy-constrained wireless networks, has attracted lots of attention. In this letter, we consider an energy-harvesting multiple-relay multiple-input multiple-output (MIMO) decode-and-forward (DF) cooperation network. A joint relay-and-antenna selection (JRAS) scheme, which jointly determines the best transmit antenna at the source node, the best relay, and the best transmit antenna at the selected relay, is proposed to minimize the system outage probability. Then, we analyze the outage performance of the JRAS scheme, and the exact expression for the outage probability is derived. Finally, simulation results show the correctness of the theoretical analysis and the superiority of the JRAS scheme.
