Professor Ishibashi gave a special guest lecture about RF energy harvesting and cooperative communications at Jacobs University Bremen in Bremen, Germany on Dec 8, 2014.

Abstract: In this talk, 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-harvest-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. We analyze the DHF cooperation from the aspect of diversity-multiplexing tradeoff (DMT) and prove that it can achieve diversity order of two. Also, some open issues regarding cooperative diversity with RF energy harvesting are presented.
