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.
