In this paper, we provide an overview of radio frequency (RF) energy harvesting technology, which scavenges the energy from ambient radio signals. As an example of wireless-powered cooperative diversity, we introduce dynamic-har- vest-and-forward (DHF) cooperation which enables to obtain diversity gain with consuming neither extra energy nor extra bandwidth by exploiting the relay ?s proximity advantage over the destination. Numerical results show that the DHF coopera- tion can achieve the diversity order of two. Also, some open issues regarding cooperative diversity with RF energy harvesting are presented. |
