Our member, Hiroki Kawabata, gave presentation titled “Analysis of Energy Harvesting Relay Selection Using Channel Distribution Information” at IEICE SR, Akashi, Japan.
Our members, Hiroki Kawabata and Shun Ogata gave presentations titled “A study on energy harvesting relay selection using channel distribution information” and “Optimization of the target degree of frameless ALOHA,” respectively at the 2015 IEICE General Conference.
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.
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.
