摘要

In this study, the authors first propose two protocols, namely the opportunistic relay (OR) priority and the direct retransmission (DR) priority, based on the reactive and proactive OR selection schemes, respectively. Then, they investigate the outage performance of these protocols with outdated channel state information (CSI) and derive the exact closed-form expressions of the outage probabilitie...
