Prof. Ioannis Krikidis from Cyprus visited our laboratory on 15th July and we fully enjoyed fruitful discussions.
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 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.
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.

Assistant Professor Koji Ishibashi was promoted to Associate Professor on Dec. 1 2014.

Thank you for your interest in our laboratory.
We are investigating vast area of communication technologies in order to make our world more fascinating. We are now working on several projects on RF energy harvesting, cooperative communications, rateless coding, and advanced network coding in collaboration with professors and researchers not only in Japan but also in foreign countries such as Germany, Korea, United States, and so on.
Thus, our laboratory applicants should be:
- able to work with people with different cultures;
- able to work in an engineering environment; and
- proficient at computer programming and/or mathematics
f you are interested in working with me, please join an AWCC orientation that will be held at 2:00pm at room 319 in E-10 building on Nov. 21 or 22 and get contact with me via email.
We are very excited to have launched our new website.
