2015年3月に東京工業大学で開催されたRCS研究会において、修士2年 武石直樹君、修士1年 尾形 駿君が下記のテーマで発表を行いました。
“分散多次元空間結合Repeat-Accumulate符号”, 武石直樹, 石橋功至, アブレウ ジュゼッペ
“フレームレスALOHAにおけるターゲット重み分布の密度発展法を用いた最適化”, 尾形 駿, アブレウ ジュゼッペ, 石橋功至
Our members, Naoki Takeishi and Shun Ogata gave presentations about distributed multi-dimensional spatially coupled Repeat-Accumulate code and optimization of target degree distribution using density evolution for frameless ALOHA, respectively at IEICE RCS, Tokyo, Japan.
Our paper entitled “spatially-coupled repeat accumulate coded cooperation” has been accepted to IEEE WCNC’15 will be held at New Orleans, LA.

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.
