Prof. Abreu: New visiting professor.

Prof. Giuseppe Abreu from Jacobs University Bremen, Germany, is now visiting our laboratory.

He will stay until the end of August and we have started a joint research project about the secrecy capacity.

Our paper has been accepted to IEEE WCNC’15.

Our paper entitled “spatially-coupled repeat accumulate coded cooperation” has been accepted to IEEE WCNC’15 will be held at New Orleans, LA.

The program of Track1 (PHY and Fundamentals) is available at the following website:

The paper proposes the effective technique to simultaneously obtain the diversity and coding gain even when both the number of users and the length of information packets are limited. The proposed approach significantly improves the decoding performance compared with conventional cooperative techniques.

Special Guest Lecture @ Jacobs University Bremen

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.
