Mr. Ade Irawan, a School of Information Science doctoral student, received the Student Paper Award from IEEE Vehicular Technology Society Japan Chapter.

Mr. Ade Irawan, a 3rd year doctoral student in Information Theory and Signal Processing, School of Information Science,received the Student Paper Award from IEEE Vehicular Technology Society Japan Chapter for his paper on wireless communication theory presented at the 2015 IEEE 82nd Vehicular Technology Conference (VTC), held in Boston (VTC 2015-Fall), USA. IEEE Vehicular Technology Conference (VTC) is a flagship conference of the Vehicular Technology Society (VTS), which takes place twice a year, once in outside the northern America and the other in northern America. Each VTC receives more than 1000 paper submissions, and VTC 2015-Fall accepted 415 papers. The accepted and presented papers are all published in IEEE Xplore. Of the 415 papers, 34 papers from Japan, and of the 34 papers, 24 from academia. The accepted papers from the Japanese academia are further evaluated by the external evaluators, appointed by the IEEE Japan Chapter, and Student Award Papers are selected. The selection process is known to be very strict and rigorous, according to the IEEE region activity bylaw.

IEEE VTS covers all technologies related to mobility, including mobile wireless communications, sensor networks, Internet of Things, Vehicle to Vehicle Communications, Transportation, and Auto-motives.

[Title] "Lossy Forwarding Technique for Parallel Multihop-Multirelay Systems".
[Author] Ade Irawan, Khoirul Anwar, and Tad Matsumoto
[Abstract] This paper proposes a Partial Hybrid Automatic Repeat reQuest (P-HARQ) scheme where the relaying nodes select either forwarding the erroneous packets or requesting retransmission. In contrast to the conventional technique where the erroneous packets is always discarded, the packets found to have errors after decoding are interleaved, re-encoded, and forwarded if relay selects the forwarding mode. This technique is refer to as lossy forwarding. In this paper, the mode selection (either forwarding or requesting retransmission) is based on the confidence indicator (CI). Since the channels are assumed to suffer from block Rayleigh fading, the CI is calculated via online mutual information measurements, block-by-block. Results of computer simulations conducted to confirm the superiority of the proposed P-HARQ technique in terms of bit-error-rate, packet-error-rate and throughput performances in parallel multihop wireless multirelaying systems, are presented.
[Comment] I am very honored and grateful to receive the student paper award from IEEE Vehicular Technology Society (VTS) Japan for the paper presented at IEEE VTC 2015-Fall. This research is a part of work for FP7 RESCUE Project funded by the European Union, which is connecting JAIST with the European research communities. Accordingly, this award highly encourages and motivates me to make more research contributions in the society and international research communities. I truly appreciate JAIST for the financial support via the research grant program. Also, I would like to express my deep gratitude to the coauthors, Dr. Khoirul Anwar for his constructive discussions and inspiring encouragement, as well as Prof. Tad Matsumoto for his excellent scientific supports, and great guidance and supervision.
